Question 3: 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 95% level of confidence. Use 3 decimal places for all answers. 12.07 11.94 12 11.91 12.1 11.86 12.16 12.2 12.21 12.06 11.99 12.11 11.87 12.06 11.96 11.93 11.96
