Confriming I answered B, C, D correctly. I think I did.

Question Help A jar of peanuts is supposed to have 20 ounces of peanuts. The filling machine inevitably experiences fluctuations in filling, so a quality-control manager randomly samples 12 jars of peanuts from the storage facility and measures their contents. She obtains the accompanying data. Complete parts (a) through (d) below. Click here to view the peanut jar data. Click here to view the table of critical values of the chi-square distribution.

No Yes (b) Determine the sample standard deviation. s= .358 (Round to three decimal places as needed.) (c) Construct a 99% confidence interval for the population standard deviation of the number of ounces of peanuts. Select the correct choice below and fill in the answer boxes to complete your choice. (Use ascending order. Round to three decimal places as needed.) O A. There is a 99% chance that the true population standard deviation is between and O B. If repeated samples are taken, 99% of them will have the sample standard deviation between and Peanut jar data - X O C. There is 99% confidence that the population standard deviation is between |229| and 736 (d) The quality control manager wants the machine to have a population standard deviation below 0.20 ounce. Does the confidence interval validate this desire? 19.93 19.75 20.23 19.41 19.83 19.81 O 19.43 20.19 19.81 19.45 20.33 20.47 O A. Yes-the lower bound of the confidence interval is greater than 0.20. O B. No-the lower bound of the confidence interval is less than 0.20. O C. No-the lower bound of the confidence interval is greater than 0.20. Print Done O D. Yes-the lower bound of the confidence interval is less than 0.20. Click to select your answer(s)
