The annual earnings of 12 randomly selected computer software engineers have a sample standard deviation of $3724. Assume the sample is from a normally distributed population. Construct a confidence interval for the population variance o and the population standard deviation o. Use a 90% level of confidence. Interpret the results. What is the confidence interval for the population variance a (Round to the nearest integer as needed.) GRILLED
