Find the P-values when testing the mean. The principal of a school wants to test the average IQ of students at her school. She administers an IQ test to 64 randomly selected students. Among the sampled students, the sample average IQ is 108, and the sample standard deviation is 10.

a) What is the P-value when testing the hypothesis that the average IQ is at least 110?
P-value = (round to 4 decimals)

b) What is the P-value when testing the hypothesis that the average IQ is at most 110?
P-value = (round to 4 decimals)

c) What is the P-value when testing the hypothesis that the average IQ is not 110?
P-value = (round to 4 decimals)

Answer :

Final answer:

To find the p-values in hypothesis testing for the average IQ of students, use the standard normal distribution and calculate the test statistic, z. For each hypothesis, find the corresponding area under the standard normal distribution curve to obtain the p-value.

Explanation:

To find the p-values in hypothesis testing for the average IQ of students, we can use the standard normal distribution. The formula to calculate the test statistic, z, is given by:

z = (sample mean - hypothesized mean) / (sample standard deviation / sqrt(sample size))
