M 14 11 A container of soda is supposed to contain 1000 milliliters of soda. A quality control manager wants to be sure that the standard deviation of the soda containers is less than 20 milliliters. He randomly selects 10 cans of soda with a mean of 997 milliliters and a standard deviation of 19 milliliters, Does this suggest that the variation in the soda containers is at an acceptable level (less than 20 milliliters)? Assume that the amount of soda contain is normally distributed. Use a = 0.05. [Make sure to provide the null and alternative hypotheses, the appropriate test statistic, p-value or critical value, decision, and conclusion.] Show work. 12pt Vil T A
