Conduct the appropriate hypothesis test and compute the test statistic. Previous data suggests that the average cost of a home-cooked Thanksgiving meal for ten is $49.00 A consumer research group believes, however, that this number has increased due to slightly higher food costs. In order to verify their hunch, they decide to perform a Hypothesis Test and collect data on 25 consumers who were preparing a home-cooked Thanksgiving meal for ten. The sample results in an average cost of $51.00 with a sample standard deviation of $5.00. Assuming that the cost of meal preparation is normally distributed, perform the appropriate hypothesis test at a 0.05 significance level to determine whether there is sufficient evidence that the meal-cost has increased. No, because the test statistic is 2.00 No, because the test statistic is 1.645 Yes, because the test statistic is 1.645 Cannot be determined Yes, because the test statistic is 2.00
