ting times (in minutes) of a random sample of 20 people at a bank have a sample standard deviation of 4.5 minutes. Construct a confidence interval for the population variance of and the population standard deviation g. Us confidence. Assume the sample is from a normally distributed population. the confidence interval for the population variance ?? (Round to one decimal place as needed.) the results. Select the correct choice below and fill in the answer box(es) to complete your choice. o one decimal place as needed.) With 90% confidence, you can say that the population variance is greater than O B. With 90% confidence, you can say that the population variance is between and With 10% confidence, you can say that the population variance is less than O D. With 10% confidence, you can say that the population variance is between and he confidence interval for the population standard deviation o? (Round to one decimal place as needed.) the results. Select the correct choice below and fill in the answer box(es) to complete your choice. o one decimal place as needed.) With 90% confidence, you can say that the population standard deviation is between and minutes. O B. With 90% confidence, you can say that the population standard deviation is less than minutes. With 10% confidence, you can say that the population standard deviation is between minutes and O D. With 10% confidence, you can say that the population standard deviation is greater than minutes. inutes
