Suppose a 2018 study randomly sampled 32 A age 50+ and found an average annual expenditure on restaurant food of $1945 with a standard deviation of sa00, Is there reason to believe that the avera 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 O b. None of the answers is correct OC. 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.
