1855 program claims that program participants have a mean weight loss of at least 11 pounds after 1 month. You work for a medical association and are asked to test this claim. A random sample of 30 program participants and their weight losses (in pounds) after 1 month is listed in the table below. Assume the population standard deviation is 3. At a = 0.03, do you have enough evidence to reject the program's claim? Complete parts (a) through (e). 5.6 6 6.2 6.3 7.1 7.8 7.9 8.2 8.3 8.7 D 8.8 9.2 9.3 9.5 9.7 9.9 10.3 10.4 10.5 10.6 10.8 11.2 11.3 11.3 11.4 12 12.7 12.9 13.6 15.3 Identify the rejection region(s). Choose the correct answer below. A. B. Fail to reject Ho- Q Fail to reject Ho C. Fail to reject Ho. AAA Reject Ho Reject Ho -4 Reject Ho Reject Ho- (c) Find the standardized test statistic. z= ☐ (Round to two decimal places as needed.)
