A company that makes cola drinks states that the mean caffeine content per 12-ounce bottle of cola is 55 milligrams. You want to test this claim. During your tests, you find that a random sample of thirty 12-ounce bottles of cola has a mean caffeine content of 54.1 milligrams. Assume the population is normally distributed and the population standard deviation is 7.3 milligrams. At a = 0.08, can you reject the company's claim? Complete parts (a) through (e). (a) Identify Ho and H. Choose the correct answer below. OA. Ho: = 54.1 H 54.1 OC. Ho: us 55 Hiu> 55 OB. Ho: p54.1 H= 54.1 OD. Ho: us 54.1 Hu> 54.1 OF. Ho: u55 OE Ho: 55 Hu55 H 55 (b) Find the critical value(s). Select the correct choice below and fill in the answer box within your choice. (Round to two decimal places as needed.) O A. The critical value is O B. The critical values are t Fail to reject Ho- Oc. Fail to reject Ho Fail to reject H Reject Ho Q Reject Ho/ Reject Ho Reject Ho- (c) Find the standardized test statistic. z= (Round to two decimal places as needed.) (d) Decide whether to reject or fail to reject the null hypothesis. O A. Since z is in the rejection region, reject the null hypothesis. B. Since z is not in the rejection region, fail to reject the null hypothesis. C. Since z is in the rejection region, fail to reject the null hypothesis. D. Since z is not in the rejection region, reject the null hypothesis. (e) Interpret the decision in the context of the original claim. At the 8% significance level, there Venough evidence to V the company's claim that the mean caffeine content per 12-ounce bottle of cola milligrams.
