A fast food restaurant estimates that the mean sodium content in one of its breakfast sandwiches is no more than 919 milligrams. A random sample of 42 breakfast sandwiches has a mean sodium content of 914 milligrams. Assume the population standard deviation is 19 milligrams. At a = 0.01, do you have enough evidence to reject the restaurant's claim? Complete parts (a) through (e). (a) Identify the null hypothesis and alternative hypothesis. O A. Ho: µs 919 (claim) Hai u> 919 O B. Ho: H<914 (claim) OC. Ho: u= 914 (claim) Ha: u2914 Ha: u#914 OF. Ho: u>919 O D. Ho: µ#919 (claim) Ha:u = 919 O E. Ho: us914 Hai H<914 (claim) Hai us919 (claim) (b) Identify the critical value(s). Use technology. Zo =U (Use a comma to separate answers as needed. Round to two decimal places as needed.) Identify the rejection region(s). Select the correct choice below. O A. The rejection regions are z> 2.33 and z< - 2.33. O B. The rejection region is z<2.33. O C. The rejection region is z> 2.33. (c) Identify the standardized test statistic. Use technology. (Round to two decimal places as needed.) (d) Decide whether to reject or fail to reject the null hypothesis, and (e) interpret the decision in the context of the original claim. O A. Fail to reject Ho. There is sufficient evidence to reject the claim that mean B. Reject Ho.
