Question

The prices of a random sample of 24 new motorcycles have a sample standard deviation of $3656. Assume the sample is from a normally distributed population. Construct a confidence interval for the population variance  2 and the population standard deviation . Use a 99% level of confidence. Interpret the results.

What is the confidence interval for the population variance  2 ? (____,____) (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.)

With 1% confidence, you can say that the population variance is between ____ and ____.
