Workers at a certain soda drink factory collected data on the volumes (in ounces) of simple random sample of 15 cans of the soda drink Those volumes have mean of 12.19 oz and a standard deviation of 0.14 oz and they appear be from a normally distributed population. If the workers Want the filling process to work so that almost all cans have volume between 11.88 and 12.52, and the standard deviation should be less than 0.16 oz. use the sample data test that claim that the population of volumes has a standard deviation less than 0.16. Use a 0.025 significance level. B) compute the test statistic

Workers at a certain soda drink factory collected data on the volumes (in ounces) of a simple random sample of 15 cans of the soda drink. Those volumes have a mean of 12.19 oz and a standard deviation of 0.14 oz, and they appear to be from a normally distributed population. If the workers want the filling process to work so that almost all cans have volumes between 11.88 oz and 12 52 oz, the range rule of thumb can be used to estimate that the standard deviation should be less than 0.16 oz. Use the sample data to test the claim that the population of volumes has a standard deviation less than 0.16 oz. Use a 0.025 significance level. Complete parts (a) through (d) below a. Identify the null and alternative hypotheses. Choose the correct answer below. O A. Ho > 0.16 oz B. HO0.16 oz H0.16 02 Ho<0.16 oz OCH 0.16 02 OD. H 2016 2 H, 670.16 oz Ho<0.16 oz b. Compute the lost statistic (Round to three decimal places as needed)
