The annual earnings of 13 randomly selected computer software engineers have a sample standard deviation of $3697. Assume the sample is from a normally distributed population. Construct a confidence interval for the population variar and the population standard deviation a. Use a 95% level of confidence. Interpret the results. What is the confidence interval for the population variance o2? OD (Round to the nearest integer as needed.) Interpret the results. Select the correct choice below and fill in the answer box(es) to complete your choice. (Round to the nearest integer as needed.) O A. With 5% confidence, you can say that the population variance is less than O B. With 5% confidence, you can say that the population variance is between and OC. With 95% confidence, you can say that the population variance is between OD.
