Please find the confidence interval for the population variance is ( , ) and ) the confidence interval for the population standard deviation is ( , )

The prices of a random sample of 20 new motorcycles have a sample standard deviation of $3648. Assume the sample is from a normally distributed population. Construct a confidence interval for the population variance of and the population standard deviation o. Use a 95% level of confidence. Interpret the results. What is the confidence interval for the population variance o?? ((Round to the nearest integer as needed.)
