The waiting times (in minutes) of a random sample of 22 people at a bank have a sample standard deviation of 3.9 Question list K minutes. Construct a confidence interval for the population variance of and the population standard deviation o. Use a 95% level of confidence. Assume the sample is from a normally distributed population. Question 1 What is the confidence interval for the population variance o2? Question 2 ([.[)(Round to one decimal place as needed.) Interpret the results. Select the correct choice below and fill in the answer box(es) to complete your choice. (Round to one decimal place as needed.) Question 3 O A. With 95% confidence, you can say that the O B. With 95% confidence, you can say that the population variance is between and population variance is greater than Question 4 O C. With 5% confidence, you can say that the O D. With 5% confidence, you can say that the population variance is between and population variance is less than O Question 5 What is the confidence interval for the population standard deviation o?
