Extracted text: 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 17 containers. Estimate the population standard deviation at a 98% level of confidence. 11.99 12.01 11.71 12.1 11.96 12 11.86 11.96 12.15 12.07 12.17 12.14 11.84 11.87 11.99 12.08 11.97 (Data checksum: 203.87) Note: Keep as many decimats as possible while making these calculations. If possible, keep all answers exact by storing answers as variables on your calculator-or computer. a) Find the sample standard deviation: b) Find the lower and upper x critical values at 98% confidence: Lower: Upper: c) Report your confidence interval for o:
