Question

You work for a soft-drink company in the quality control division. You are interested in the standard deviation of one of your production lines as a measure of consistency. The product is intended to have a mean of 12 ounces, and your team would like the standard deviation to be as low as possible. You gather a random sample of 15 containers. Estimate the population standard deviation at a 80% level of confidence.

11.86	12.12	12.2	12.08	12.06
12.09	11.92	12.26	12.04	12.1
11.85	11.97	11.85	12	12.01

(Data checksum: 180.41)

Keep as many decimals as possible while making these calculations.

a) Find the sample standard deviation:

b) Find the lower and upper χ2χ2 critical values at 80% confidence:
Lower: Upper:

c) Report your confidence interval for σσ:
