The waiting times (in minutes) of a random sample of 20 people at a bank have a sample standard deviation of 4.4 minutes. Construct a confidence interval for the populationvariance o² and the population standard deviation o. Use a 95% level of confidence. Assume the sample is from a normally distributed population.OC. With 95% confidence, you can say that the population variance is betweenandO A. With 5% confidence, you can say that the population standard deviation isgreater thanminutes.COXWhat is the confidence interval for the population standard deviation o?(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.)OC. With 5% confidence, you can say that the population standard deviation isbetween minutes and minutes.O D. With 5% confidence, you can say that the population variance is less thanOB. With 95% confidence, you can say that the population standard deviation is lessthanminutes.OD. With 95% confidence, you can say that the population standard deviation isbetween and minutes.
