A particular fruit's weights are normally distributed, with a mean of 290 grams and a standard deviation of 40 grams.
The heaviest 13% of fruits weigh more than how many grams?
We can start by using the standard normal distribution to find the corresponding z-score for the 13th percentile.
Using a standard normal distribution table, we find that the z-score corresponding to the 13th percentile is approximately -1.04.
Now we can use the z-score formula to find the weight of the fruit corresponding to this z-score:
z = (x - μ) / σ
where z is the z-score, x is the weight of the fruit we want to find, μ is the mean weight of the fruit, and σ is the standard deviation of the fruit's weight.
Rearranging the formula to solve for x, we get:
x = z * σ + μ
Plugging in the values we have, we get:
x = -1.04 * 40 + 290 = 250.4
Therefore, the heaviest 13% of fruits weigh more than 250.4 grams.
As per the given data, the heaviest 13% of fruits weigh more than approximately 335.4 grams.
What is standard deviation?A standard deviation is a measure of how far apart the data is from the mean.
A low standard deviation indicates that data is clustered around the mean, whereas a high standard deviation indicates that data is more spread out.
To solve this problem, we need to use the inverse normal cumulative distribution function. We want to find the weight that corresponds to the 87th percentile (100% - 13%), which we can express as a z-score:
z = invNorm(0.87) ≈ 1.135
We can then use the formula for a standardized normal distribution to find the weight:
z = (x - μ) / σ
Rearranging this formula to solve for x, we get:
x = z * σ + μ
Plugging in the values we know, we get:
x = 1.135 * 40 + 290 ≈ 335.4 grams
Therefore, the heaviest 13% of fruits weigh more than approximately 335.4 grams.

Explanation:
The population in question consists of the high temperatures recorded in the city of Ukiah during 200 randomly selected days in September over the past century.
The sample size is 200 days in September with their respective high temperatures recorded in Ukiah over the past century.
The measures of central tendency for the sample are M = 81.9 Fahrenheit, which represents the mean high temperature for the 200 days.
The measures of variability for the sample include the range of temperatures recorded, from the lowest of 52 F to the highest of 107 F.
The mean high temperature for the 200 days is M = 81.9 Fahrenheit.
The range of high temperatures recorded in the sample is from the lowest of 52 F to the highest of 107 F.
The standard deviation for the sample is s = 7.4 Fahrenheit, which indicates the degree of variability of the high temperatures around the mean of 81.9 Fahrenheit.
The variance for the sample is s^2 = 54.76 Fahrenheit^2, which is the square of the standard deviation and measures the spread of the high temperatures from the mean.

Three cards are drawn from a standard deck of cards and not replaced.
What is the probability that the first card is a King and the last two cards are Queens? Write your answer as a simplified fraction.
Are the events independent? Explain.
The probability that the first card is a King and the last two cards are Queens when three cards are drawn from a standard deck without replacement is 1/5525, and the events are not independent.
What is a deck of cards?
A deck of cards is a collection of 52 rectangular-shaped cards, usually made of paper or plastic, that are used to play various card games. The deck is divided into four suits (clubs, diamonds, hearts, and spades), with each suit containing 13 cards (Ace, 2, 3, 4, 5, 6, 7, 8, 9, 10, Jack, Queen, and King). In some card games, such as poker, the Ace can be used as a high or low card, depending on the rules of the game. The deck of cards also includes two Jokers, which are often used as wild cards in certain games.
The probability of drawing a King on the first card is 4/52 (since there are 4 Kings in a deck of 52 cards).
After the first King is drawn, there are 51 cards remaining, of which 4 are Queens. So the probability of drawing a Queen on the second card is 4/51.
After the second Queen is drawn, there are 50 cards remaining, of which 3 are Queens. So the probability of drawing a Queen on the third card is 3/50.
To find the probability of all three events happening together, we multiply the probabilities of each event:
(4/52) * (4/51) * (3/50) = 1/5525
Therefore, the probability that the first card is a King and the last two cards are Queens is 1/5525.
The events of drawing the King and the Queens are not independent because the probability of drawing the Queens depends on whether or not a King was drawn first. If a King was drawn first, then there are fewer cards left in the deck, which changes the probability of drawing a Queen on the second and third cards.

One of the functions of sociology of education is the development of new social patterns (see p5 in SoE). Briefly discuss how this aim could be taught in the classroom. (3)
Teaching the aim of developing new social patterns within the context of the sociology of education requires a comprehensive and interactive approach in the classroom.
Some strategies that could be used to effectively teach this aim:
1)Introduce case studies: Presenting real-life case studies that demonstrate social patterns and their consequences can help students understand the importance of developing new social patterns.
By analyzing these cases, students can identify existing social patterns, evaluate their impacts, and brainstorm potential alternatives.
2)Encourage critical thinking: Foster critical thinking skills by engaging students in discussions and debates about current social patterns and their implications.
Encourage them to question the status quo, challenge existing norms, and explore alternative social arrangements.
This can be done through open-ended questions, group activities, and analyzing conflicting viewpoints.
3)Collaborative projects: Assigning collaborative projects that require students to propose and develop new social patterns can be an effective way to engage them in active learning.
Students can work in groups to identify social issues, research potential solutions, and create action plans for implementing new social patterns.
This hands-on approach encourages creativity, teamwork, and problem-solving skills.
4)Guest speakers and field trips: Inviting guest speakers from various fields, such as sociology, education, and community organizations, can provide students with real-world insights into the development of new social patterns.
Organizing field trips to relevant community organizations or institutions can also give students the opportunity to observe and learn from initiatives that aim to create positive social change.
5)Reflective activities: Incorporate reflective activities, such as journaling, class discussions, or personal presentations, where students can express their thoughts, insights, and personal experiences related to social patterns.
Encourage them to critically reflect on their own behaviors, attitudes, and the potential impact they can have on social patterns.

In a publishing company that prints products of varying dimensions, workers manually cut paper rolls into the required sizes. The company's management wants to install a computer-controlled system to do this task. If the system is installed, the employees would only need to enter the required paper dimensions into a computer, and a machine would cut the paper. How would the computer-controlled system be better than the manual system used by the publishing company?
Answer:
The computer-controlled system would likely be better than the manual system used by the publishing company in several ways:
Precision: The computer-controlled system would be more precise and accurate than manual cutting. It can measure and cut the paper rolls with greater accuracy, reducing the likelihood of errors or waste.
Efficiency: The computer-controlled system can cut the paper rolls faster and more efficiently than manual cutting. This would increase the productivity of the workers and enable the company to produce more products in less time.
Consistency: The computer-controlled system would ensure consistent quality of the cut paper rolls. This is because the machine is programmed to cut the paper in the exact same way every time, which means that there is less room for human error or variation.
Safety: The computer-controlled system would be safer for the workers than manual cutting. It reduces the risk of injury from accidents or repetitive strain injuries associated with manual cutting.
Overall, the computer-controlled system would provide significant benefits for the publishing company in terms of precision, efficiency, consistency, and safety.

1. In a study of crime, the FBI found that 13.2% of all Americans had been victims of crime during a one-year period. This result was based on a sample of 1,105 adults. (a) Estimate the percentage of US adults who were victims at the 90% confidence level. (b) Estimate the percentage of US adults who were victims at the 99% confidence level.
Answer:
(a) The estimate the percentage of US adults who were victims at the 90% confidence level is (12%, 15%).
(b) The estimate the percentage of US adults who were victims at the 99% confidence level is (11%, 16%).
Explanation:
The percentage of Americans who had been victims of crime during a one-year period is, \(\hat p=0.132\).
The sample selected was of size, n = 1105.
The (1 - α)% confidence interval for the population proportion is:
\(CI=\hat p\pm z_{\alpha/2}\cdot \sqrt{\frac{\hat p(1-\hat p)}{n}}\)
(a)
The confidence level is 90%.
The critical value of z for 90% confidence level is, z = 1.645.
Compute the 90% confidence interval for the percentage of US adults who were victims as follows:
\(CI=\hat p\pm z_{\alpha/2}\cdot \sqrt{\frac{\hat p(1-\hat p)}{n}}\)
\(=0.132\pm 1.645\times\sqrt{\frac{0.132(1-0.132)}{1105}}\\\\=0.132\pm 0.0168\\\\=(0.1152, 0.1488)\\\\\approx (0.12, 0.15)\)
Thus, the estimate the percentage of US adults who were victims at the 90% confidence level is (12%, 15%).
(b)
The confidence level is 99%.
The critical value of z for 99% confidence level is, z = 2.58.
Compute the 99% confidence interval for the percentage of US adults who were victims as follows:
\(CI=\hat p\pm z_{\alpha/2}\cdot \sqrt{\frac{\hat p(1-\hat p)}{n}}\)
\(=0.132\pm 2.58\times\sqrt{\frac{0.132(1-0.132)}{1105}}\\\\=0.132\pm 0.0263\\\\=(0.1057, 0.1583)\\\\\approx (0.11, 0.16)\)
Thus, the estimate the percentage of US adults who were victims at the 99% confidence level is (11%, 16%).
Clarence wants to estimate the percentage of students who live more than three miles from the school. He wants to create a
98%
confidence interval which has an error bound of at most
4%
. How many students should be polled to create the confidence interval?
Answer:
847 students must be interviewed.
Explanation:
To reach this result we will use the following formula:
\(n = \frac{z^2*p*(1-p)}{e^2}\)
In this formula the letter "e" is equal to 0.04 (4%). Thus, we must find the values of "p" and "z", to find the "n", which refers to the confidence interval.
The question above did not show us what value should be used in "p". When we do not have information on this value, it is always recommended to use 0.5, which is the sample maximization value.
In the situation shown in the question above, a confidence interval of 98% is presented. Thus, it is implicit that we must adopt in "z" a value among the cumulative values of the z distribution of up to 1% or up to 99%. That way you can use any value between the range of 1% to 99%, you should look for that value in a table of Z, however, to facilitate the calculation we will use a value of the area of 99% in the distribution of z. This value is 2,327.
Now we can replace these values in the formula and find the value of "n".
\(n = \frac{2.327^2*0.5*(1-0.5)}{0.04^2} = 846.08\)
As there are no 0.8 students, we must round the number to 487. So we can say that it will be necessary to interview 847 students to create the confidence interval.
