Construct a confidence interval for:a. the population varianceb. the population standard

Construct a confidence interval for:

a. the population variance

b. the population standard deviation

Use a 99% level of confidence.

K The waiting times (in minutes) of a random sample of 22 people at a bank have a sample standard deviation of 3.8 Question list minutes. Construct a confidence interval for the population variance of and the population standard deviation o. Use a 99% level of confidence. Assume the sample is from a normally distributed population. O Question 8 What is the confidence interval for the population variance o2? [.[)(Round to one decimal place as needed.) O Question 9 O Question 10
