A process of analysing, purifying, manipulating, and modelling data in order to find relevant information, come to conclusions, and enhance decision-making is known as data analytics.

It entails posing queries and providing answers utilising quantitative and statistical methods for explanatory and prescriptive analysis. Descriptive, diagnostic, predictive, and prescriptive analytics are the four basic categories of data analysis.

Diagnostic analytics is used to determine the reason why something occurred, whereas descriptive analytics is used to report what has already occurred.

The use of predictive analytics, on the other hand, enables the prediction of likely future events. Last but not least, prescriptive analytics is employed to decide what steps should be taken in order to accomplish a particular result or goal in light of the knowledge gleaned from descriptive, diagnostic, and predictive analytics.

By using these different types of analytics, individuals will be able to gather and analyze data to better understand trends, identify problems, and make informed decisions.

Step-by-step explanation:

find the proportion and solve for the volume.

The percentage of Hospital A patients that died is 3% and the percentage of Hospital B patients that died is 2%. Hospital B is potentially safer based on the provided data.

To find the percentage of Hospital A patients who died, we need to divide the number of patients who died by the total number of patients in Hospital A and multiply by 100 to get a percentage. The same process applies for Hospital B.

For Hospital A:
- Number of patients who died = 63
- Total number of patients = 2100
- Percent of patients who died = (63/2100) x 100 = 3%

For Hospital B:
- Number of patients who died = 16
- Total number of patients = 800
- Percent of patients who died = (16/800) x 100 = 2%

Therefore, 3% of Hospital A patients died and 2% of Hospital B patients died.

Based on this data, Hospital B has a lower percentage of patients who died after surgery, making it potentially safer in terms of patient outcomes. However, it is important to consider other factors as well, such as the types of surgeries performed and the overall health of the patients before making a final decision about which hospital is safer.

Answer:

for A=\(\frac{7b-7}{6}\) and for B=\(\frac{6a+7}{7}\)

Step-by-step explanation:

For A

\(\left(6a-3\right)=\left(7b-10\right)\)

\(6a-3+3=7b-10+3\)

\(6a=7b-7\)

\(\frac{6a}{6}=\frac{7b}{6}-\frac{7}{6}\)

\(a=\frac{7b-7}{6}\)

For B

\(\left(6a-3\right)=\left(7b-10\right)\)

\(7b-10=\left(6a-3\right)\)

\(7b-10=6a-3\)

\(7b-10+10=6a-3+10\)

\(7b=6a+7\)

\(\frac{7b}{7}=\frac{6a}{7}+\frac{7}{7}\)

\(b=\frac{6a+7}{7}\)

A) The probability of a z-score of 0.5909 or higher is 0.0808.

B) The probability of a three-year return of 10% or less is 0.3413.

C) A return of at least 18.91% would put a domestic stock fund in the top 15% for the three-year period.

(a) The probability that an individual large-cap domestic stock fund had a three-year return of at least 17% is 0.0808.

To calculate this probability, we can use the z-score formula:

z = (x - μ) / σ

Where:

x = 17%

μ = 14.4%

σ = 4.4%

z = (17% - 14.4%) / 4.4% = 0.5909

Using a standard normal distribution table or calculator, we can find that the probability of a z-score of 0.5909 or higher is 0.0808.

(b) The probability that an individual large-cap domestic stock fund had a three-year return of 10% or less is 0.1151.

Using the same formula and substituting x = 10%, we get:

z = (10% - 14.4%) / 4.4% = -1.0000

The probability of a z-score of -1.0000 or lower is 0.1587. However, we want the probability of a return of 10% or less, so we need to subtract this probability from 0.5 (since the normal distribution is symmetric around 0) and round to four decimal places:

P(z ≤ -1.0000) = 0.1587

P(z ≥ 1.0000) = 0.1587

P(z ≤ -1.0000) + P(z ≥ 1.0000) = 0.3174

1 - 0.3174 = 0.6826

0.6826 / 2 = 0.3413

So, the probability of a three-year return of 10% or less is 0.3413.

(c) To be in the top 15% of large-cap domestic stock funds for the three-year period, a fund's return would need to be at least 18.91%.

To find this value, we need to find the z-score that corresponds to the top 15% of the distribution, which is 1.0364 (found using a standard normal distribution table or calculator). Then, we can use the z-score formula to solve for x:

1.0364 = (x - 14.4%) / 4.4%

x - 14.4% = 1.0364 * 4.4%

x = 18.91%

Therefore, a return of at least 18.91% would put a domestic stock fund in the top 15% for the three-year period.

Adam Vinatieri made 14 field goals and 7 extra points.

Given that,

a field goal is 3 points and the field goal after a touchdown is only 1 point.

Adam Vinatieri made 21 field goals and extra point kicks for 49 points.

Let x be the number of field goals and y be the extra point kicks.

So we get,

x + y = 21 -------------(1)

3x + y = 49 -----------(2)

Subtracting equation (1) from equation (2),

2x = 28

 x = 14

putting the value of x in equation (1),

14 + y = 21

       y = 7

Therefore Adam Vinatieri made 14 field goals and 7 extra points.

Field goal means a score of three points in football made by drop kicking or placekicking the ball over the crossbar from ordinary play. A field goal is a successful kick of the ball by a kicker through the goalpost. It is an offensive play that can score three points for a team.

The 95% confidence interval interpretation is as follows:

The 95% confidence interval means that  we can be 95% confident that the true population mean systolic blood pressure falls within the range (114 mmHg, 120 mmHg).

However, it is important to note that the confidence interval does not tell us with certainty where the true population mean systolic blood pressure lies, only where it is likely to be.

If we obtained a different set of 100 patients, we would likely obtain a different confidence interval. This is because the sample mean and standard deviation used to compute the interval would be different. However, if the new sample is still a representative sample of the same population, we would expect the confidence interval to be similar in width and location.

If we wanted a 99% confidence interval, the interval would be wider. This is because a higher confidence level requires a wider interval to be able to capture the true population mean with a higher degree of confidence.

The exact width of the interval would depend on the sample size and standard deviation used to compute it.

The ratios of (a) square kens to square meters (1 ken² / 1 m²) is 3.88

For given question,

We have been given the unit conversion.

A traditional unit of length in Japan is the ken

and 1 ken = 1.97 m

We need to find the the ratios of (a) square kens to square meters.

First we find the square of 1 ken.

⇒ 1 square kens = (1.97 m)²

⇒ 1 square kens = 1.97 × 1.97 m²

⇒ 1 square kens = 3.88 m²                  ..................(1)

And 1 square meters = 1 m²                 ................. (2)

Now we take the ratio of square kens to square meters.

From (1) and (2),

⇒ 1 ken² / 1 m² = 3.88 / 1

⇒ 1 ken² / 1 m² = 3.88

Therefore, the ratios of (a) square kens to square meters (1 ken² / 1 m²) is 3.88

Answer:

There are 2 solutions to square root x = 9

They are 3, and -3

Step-by-step explanation:

The square root of x=9 has 2 solutions,

The square root means, for a given number, (in our case 9) what number times itself equals the given number,

Or, squaring (i.e multiplying with itself) what number would give the given number,

so, we have to find the solutions to \(\sqrt{9}\)

since we know that,

\((3)(3) = 9\\and,\\(-3)(-3) = 9\)

hence if we square either 3 or -3, we get 9

Hence the solutions are 3, and -3

Step-by-step explanation:

when x=1, y should = 2

2(1)=2

so y=2x is correct

The probability that an answer is Ann's given that it is correct is 0.43 or 43%.

Where P(A|C) is the probability that the answer is Ann's given that it is correct, P(C|A) is the probability that the answer is correct given that it is Ann's, P(A) is the probability that the answer is Ann's, and P(C) is the probability that the answer is correct.

We can use Bayes' theorem to calculate the probability that an answer is Ann's, given that it is correct:

P(A|C) = P(C|A) * P(A) / P(C)

We are given that Brandon answered 80% of the questions correctly, so the probability that the answer is correct is:

P(C) = 0.8(0.6) + 0.85(0.4) = 0.79

where 0.6 is the probability that Brandon answers a question correctly (since 40% fail), and 0.4 is the probability that Ann answers a question correctly.

We are also given that Ann usually gets 85% of the questions right, so the probability that the answer is Ann's is:

P(A) = 0.4

Finally, the probability that an answer is correct given that it is Ann's is simply:

P(C|A) = 0.85

These values are what we obtain when we apply Bayes' theorem to them:

P(A|C) = P(C|A) * P(A) / P(C)

P(A|C) = 0.85 * 0.4 / 0.79

P(A|C) = 0.43

The Bayes theorem is a mathematical formula that estimates the likelihood that an event will occur based on knowledge of comparable events that have already occurred. It is named after Reverend Thomas Bayes, an 18th-century statistician, who first formulated it.

The theorem is based on the concept of conditional probability, which is the probability of an event occurring given that another event has already occurred. Bayes' theorem provides a way to update the probability of an event based on new evidence or information. The formula for Bayes' theorem is: P(A|B) = P(B|A) * P(A) / P(B), where P(A|B) is the probability of event A given event B has occurred, P(B|A) is the probability of event B given that A has occurred, P(A) is the prior probability of A occurring, and P(B) is the prior probability of B occurring.

A result is called "statistically significant" when the p-value is less than the significant level, typically 0.05.

This means that there is less than a 5% chance that the results are due to chance alone, and suggests that there is a real effect present in the data.

The Null Hypothesis is the assumption that there is no significant difference between the measured phenomenon and a certain value or set of values. A statistically significant result means that the observed data are inconsistent with the assumption of no difference, or no effect.
