Please solve this for me, and interpret option b as well

You randomly select and measure the contents of 10 bottles of 4.214 4.293 4.257 4.249 4 185 cough syrup. The results (in fluid ounces) are shown to the right. 4 215 4.268 4.243 4 222 4.231 Assume the sample is taken from a normally distributed population. Construct 80% confidence intervals for (a) the population variance o and (b) the population standard deviation o. Interpret the results. (a) The confidence interval for the population variance is () (Round to six decimal places as needed.) Interpret the results. Select the correct choice below and fill in the answer box(es) to complete your choice (Round to six decimal place as needed.) O A. With 80% confidence, it can be said that the O B. With 20% confidence, it can be said that the population variance is greater than population variance is between and O C. With 20% confidence, it can be said that the O D. With 80% confidence, it can be said that the population variance is less than population variance is between and (b) The confidence interval for the population standard deviation is (Round to four decimal places as needed.) Interpret the results. Select the correct choice below and fill in the answer box(es) to complete your choice (Round to four decimal place as needed.) O A. With 20% confidence, you can say that the O B. With 20% confidence, you can say that the
