Is memory ability before a meal better than after a meal? Ten people were given memory tests before their meal and then again after their meal. The data is shown below. A higher score indicates a better memory ability. Score on the Memory Test Before 5 61 77 69 87 89 83 87 85 69 a Meal After 50 50 1 78 69 81 87 87 80 82 65 a Meal Assume a Normal distribution. What can be concluded at the the a = 0.01 level of significance? For this study, we should use |Select an answer a. The null and alternative hypotheses would be: Ho: Select an answer v Select an answer v Select an answer v (please enter a decimal) H1: Select an answer v Select an answer v Select an answer v (Please enter a decimal) b. The test statistic ? |= (please show your answer to 3 decimal places.) c. The p-value = (Please show your answer to 4 decimal places.) d. The p-value is ? v o e. Based on this, we should Select an answer | the null hypothesis. f. Thus, the final conclusion is that .. . The results are statistically significant at a = 0.01, so there is sufficient evidence to conclude that the population mean memory score before a meal is higher than the population mean memory score after a meal The results are statistically insignificant at a = 0.01, so there is insufficient evidence to conclude that the population mean memory score before a meal is higher than the population mean memory score after a meal. The results are statistically insignificant at o = 0.01, so there is statistically significant evidence to conclude that the population mean memory score before a meal is equal to the population mean memory score after a meal. The results are statistically significant at a = 0.01, so there is sufficient evidence to conclude that the ten memory scores from the memory tests that were taken before a meal are higher + - - + - t L
