A data set's attributes are enumerated through descriptive statistics. You can use inferential statistics to test a hypothesis or determine whether your data can be applied to a larger population.

Descriptive statistics concentrate on describing the features of a dataset that are readily evident (a population or sample). In contrast, inferential statistics concentrate on drawing conclusions or generalisations from a sample of data in a larger dataset.

The information from a research sample is described and condensed using descriptive statistics. We can draw conclusions about the larger population from which we drew our sample using inferential statistics.

The area of statistics known as descriptive statistics is focused on providing a description of the population being studied. A type of statistics known as inferential statistics concentrates on inferring information about the population from sample analysis and observation.

Hence we get the required answer.

Step-by-step explanation:

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

The amount donated to the animal shelter is $258

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

We have,

Percentage to donate to the shelter = 75%

The expression that shows the amount from the first and second craft shows.

24n + 32 _____(1)

40n + 56 ______(2)

Where n is the amount of each bracelet.

Now,

Cost of each bracelet = $4.

From (1) and (2) we get,

24 x 4 + 32 = 96 + 32 = 128

40 x 4 + 56 = 160 + 56 = 216

Now,

The total amount collected from both the craft shows.

= 128 + 216

= $344

The amount donated to the animal shelter.

= 75% of $344

= 75/100 x 344

= $258

Thus,

The amount donated to the animal shelter is $258

The smallest number by which 700 must be multiplied to make it a perfect square is 7.

To find the smallest number by which 700 must be multiplied to make it a perfect square, we need to factorize 700 first.

The prime factors of 700 are 2, 5, and 7, with 2 and 5 appearing twice and 7 appearing once.

To make 700 a perfect square, every prime factor should appear an even number of times.

However, 7 appears only once, which is odd. Thus, we need another 7 to pair up with the existing one.

Therefore, the smallest number by which 700 must be multiplied to make it a perfect square is 7.

Answer:

height = 12 feet

Step-by-step explanation:

r (radius of circle) = 7 ft

pi = 3.14 (in this context)

v = 1/3 * \(πr^{2}\) (or pi * radius squared) * h

r squared = 49 ft

v = 1/3 3.14 * 49 * h

v = 1/3 153.86 * h

3v = 153.86 * h

v = 196π

v = 615.44

3v = 1,846.32

1,846.32 = 153.86 * h

h = 12 ft.

Answer:

The expected number of planes to immediately launch is 12, and the standard deviation of the number of planes that immediately launch is approximately 1.732.

Let X be the number of planes that immediately launch. Since each plane has a probability of 0.75 of starting on the first attempt, the number of planes that immediately launch follows a binomial distribution with parameters n=16 and p=0.75.

Therefore, the expected value of X is given by

E(X) = np = 16 x 0.75 = 12

To find the standard deviation of X, we can use the formula

σ = √(np(1-p))

σ = √(16 x 0.75 x 0.25)

= √3

Dispersion in data refers to the extent of spread or variability in data points. Different measures like range, interquartile range, variance, standard deviation, skewness, and kurtosis help analyze dispersion and reveal trends, cycles, and characteristics in the data.

In data analysis, dispersion plays a crucial role in understanding the distribution of data points. The range, which is the simplest measure, provides an overview of the spread by calculating the difference between the maximum and minimum values. The interquartile range focuses on the middle 50% of the data, giving a clearer picture of the spread while ignoring outliers. Variance, the average squared deviation from the mean, offers a comprehensive understanding of dispersion, although it requires interpretation in squared units. Standard deviation, the square root of variance, is widely used as it expresses dispersion in the original unit of measurement, providing a more intuitive interpretation. Skewness and kurtosis offer insights into the shape and symmetry of the data distribution. Skewness measures the asymmetry of the distribution, indicating whether it is skewed to the left or right, while kurtosis measures the peakedness or flatness of the distribution, revealing the presence of heavy or light tails. By analyzing these dispersion measures, trends, cycles, and characteristics in the data can be identified, aiding in making informed decisions and drawing meaningful conclusions.

-29/5 is rational and can be expressed as a ratio of two integers (-29 and 5).

To show that -29/5 is rational, we need to express it as a ratio of two integers.

We know that -29 is an integer and 5 is also an integer. Therefore, we can write:

-29/5 = (-29) / 5

Since both -29 and 5 are integers, their ratio is a rational number. Therefore, -29/5 is also a rational number.

Another way to see this is to note that any fraction a/b can be written in lowest terms as:

a/b = p/q

where p and q are integers with no common factors (other than 1). To find p and q, we can simplify the fraction by dividing both the numerator and denominator by their greatest common factor (GCF). In this case, the GCF of -29 and 5 is 1, so -29/5 is already in its simplest form.

Therefore, -29/5 is rational and can be expressed as a ratio of two integers (-29 and 5).

(a) The percentage of all American males who measure success primarily from their work is approximately (0.02147, 0.03847), or 2.15% to 3.85%.

(b) The significance level associated with this inference is 1% (100% - 99% confidence level).

(c) With α = 0.1, the critical value is approximately -1.28.

(d) H0: p 0.035 (The percentage of males who define success primarily in terms of their ability to work)

Ha: p 0.035 (Less than 3.5% of males define success primarily on terms of their employment).

(a) To estimate the percentage of all American males who measure success primarily from their work, we can use the sample proportion and construct a confidence interval.

Given: Sample size (n) = 1302

Number of men who measure success primarily from their work (x) = 39

We can calculate the sample proportion (p-hat) as:

p-hat = x / n = 39 / 1302 ≈ 0.02997

To construct a confidence interval at a 99% confidence level, we can use the formula for the margin of error (E):

E = Z ×√((p-hat×(1 - p-hat)) / n)

Since the confidence level is 99%, the corresponding critical value Z can be found using a Z-table or calculator. For a 99% confidence level, Z ≈ 2.576.

Calculating the margin of error:

E = 2.576 ×√((0.02997× (1 - 0.02997)) / 1302) ≈ 0.0085

The confidence interval can be calculated as:

p-hat ± E

0.02997 ± 0.0085

Therefore, the 99% confidence interval for the percentage of all American males who measure success primarily from their work is approximately (0.02147, 0.03847), or 2.15% to 3.85%.

(b) Without conducting the hypothesis test, we can examine the confidence interval to see if it falls below the 3.5% mark. In this case, the lower bound of the confidence interval is 2.15%, which is below the 3.5% mark. Since the entire confidence interval is below 3.5%, it indicates evidence that the fraction of men who measure success primarily by their work has fallen below 3.5%. The significance level associated with this inference is 1% (100% - 99% confidence level).

(c) To carry out the hypothesis test with α = 0.1, we can use three methods: the critical value approach, the p-value approach, and the confidence interval approach.

Critical Value Approach:

State the null hypothesis (H0) and alternative hypothesis (Ha):

H0: p ≥ 0.035 (The proportion of men who measure success primarily from work is greater than or equal to 3.5%)

Ha: p < 0.035 (The proportion of men who measure success primarily from work is less than 3.5%)

Determine the significance level (α): α = 0.1

Compute the test statistic:

z = (p-hat - p) / √((p× (1 - p)) / n)

Determine the critical value for the given significance level α:

For a one-tailed test with α = 0.1, the critical value is approximately -1.28.

Compare the test statistic with the critical value:

If the test statistic is less than the critical value, reject the null hypothesis; otherwise, fail to reject the null hypothesis.

P-value Approach:

State the null hypothesis (H0) and alternative hypothesis (Ha):

H0: p ≥ 0.035 (The proportion of men who measure success primarily from work is greater than or equal to 3.5%)

Ha: p < 0.035 (The proportion of men who measure success primarily from work is less than 3.5%)
