QUESTION 10 AARP claims the average annual expenditure for Americans age 50+ on restaurant food in 2008 was $2130. Suppose a 2018 study randomly sampled 32 Am age 50+ and found an average annual expenditure on restaurant food of $1945 with a standard deviation of sa0o, Is there reason to believe that the averag expenditure for Americans age 50+ on restaurant food has decreased since 2008 at e17 For the hypothesis stated above, what is the decision? Oa, Fail to reject Ho because the test statistic is to the right of the critical value which, in this case, is negative. b. None of the answers is correct O. Reject Ho because the test statistic is to the right of the critical value which, in this case, is positive. Od. Reject Ho because the test statistic is to the left of the critical value which, in this case, is negative. Oe. Fail to reject Ho because the test statistic is to the left of the critical value which, in this case, is positive. QUESTION 11 According to a 2001 Reader's Digest article, 26% of physicians over the age of 55 have been sued at least once. Suppose you wanted to see if this percentag holds true today, so you randomly selected 50 physicians over the age of 55 and 30% indicated they had been sued at least once. Based on your findings, c conclude the proportion of all physicians over the age of 55 that have been sued at least once is now higher at a.17 Click Save and Submit to save and submit.
