The diameters (in inches) of 17 randomly selected bolts produced by a machine are listed. Use a 95% level of confidence to construct a confidence interval for (a) the population variance o and (b) the population standard deviation o. Interpret the results. 4.471 4.419 4.027 4.305 4.005 3.793 3.822 3.737 3.932 3.746 3.858 3.818 4.235 3.978 4.143 4.535 4.471 (a) The confidence interval for the population variance is (Round to three 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 three decimal places as needed.) O A. With 95% confidence, it can be said that the population variance is between and O B. With 95% confidence, it can be said that the population variance is less than O C. With 5% confidence, it can be said that the population variance is between and O D. With 5% confidence, it can be said that the population variance is greater than (b) The confidence interval for the population standard deviation is ( L ) (Round to three 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 three decimal place as needed.) O A. With 95% confidence, you can say that the population standard deviation is greater than inches O B. With 95% confidence, you can say that the population standard deviation is between and inches. O C. With 5% confidence, you can say that the population standard deviation is between and inches. O D. With 5% confidence, you can say that the population standard deviation is less than inches.
