A jar of peanut is supposed to have 16 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 obtained the following data: No. Peanut 1 2 3 4 5 6 7 8 9 10 11 12 Ounces 15.94 15.52 15.74 16.16 16.21 15.78 15.36 15.51 15.84 16.28 15.84 16.53 Determine the sample standard deviation and construct a 90% confidence interval for the population standard deviation of the number of ounces of peanuts.
