A jar of peanuts is supposed to have 12 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.

O No Yes (b) Determine the sample standard deviation. s= 0.376 (Round to three decimal places as needed.) (c) Construct a 95% 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. If repeated samples are taken, 95% of them will have the sample standard deviation between and O B. There is a 95% chance that the true population standard deviation is between and O C. There is 95% confidence that the population standard deviation is between andX Peanut jar data 11.95 11.69 12.18 11.35 11.83 11.83 11.53 12.17 11.74 11.47 12.32 12.62 Print Done
