(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) OA. There is a 95% chance that the true population standard deviation is between OB. It repeated samples are taken, 95% of them will have the sample standard deviation between C. There is 95% confidence that the population standard deviation is between 269 and 644 and and

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
