The following 96% confidence interval based on a sample of 32 students was formed to estimate the population mean time that students will require to complete a particular examination: 62.4 ± 12.6 minutes. Which one of the following interpretations is correct for this confidence interval?A) We are 96% confident that the population mean time required for all students who take this test is somewhere between 49.8 and 75.0 minutesB) We are 96% confident that the sample mean time (62.4 minutes) equals the true mean timeC) We are 96% confident that the population mean time required by students who take this test is 62.4 minutesD) We are 96% confident that the sample mean time (62.4 minutes) is correctE) We are 4% confident that an individual student taking this test will require less than 49.8 minutes or more than 75.0 minutes

A) We are 96% confident that the population mean time required for all students who take this test is somewhere between 49.8 and 75.0 minutes

Step-by-step explanation:

x% confidence interval is between a ± b.

a is the sample mean.

b is the margin of error.

Interpretation: We are x% sure that the population mean is between a-b and a+b.

In this question:

96% confidence interval for the mean time that students will require to complete a particular examination. Between 62.4 - 12.6 = 49.8 minutes and 62.4 + 12.6 = 75 minutes.

The correct interpretation is that we are 96% sure that the population mean is in this interval.

So the correct answer is:

A) We are 96% confident that the population mean time required for all students who take this test is somewhere between 49.8 and 75.0 minutes

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.
