Please answer for parts F, G, and H

g. Interpret thep-value in the context of the study. O If the sample mean memory score for the 10 people who took the test before a meal is the same as the sample mean memory score for the 10 people who took the test after a meal and if another 10 people are given a memory test before and after a meal then there would be a 20.1% chance of concluding that the mean memory score for the 10 people who took the test before a meal is at least 2,1 points lower than the mean memory score for the 10 people who took the test after a meal. Of the population mean nmemory score before a meal is the same as the population mean memory score after a meal and if another 10 people are given a memory test before and after a meal then there would be a 20.1% chance that the mean memory score for the 10 people who took the test before a meal would be at least 2.1 points lower than the mean memory score for the 10 people who took the test after a meal. O There is a 20.1% chance that the mean memory score for the 10 people who took the test before a meal is at least 2.1 points lower than the mean memory score for the 10 people who took the test after a meal. O There is a 20.1% chance of a Type l'error. h. Interpret the level of significance in the context of the study, If the population mean memory score before a meal is the same as the population mean memory score after a meal and if another 10 people are given a memory test before and after a meal, then there would be a 5% chance that we would end up falsely concuding that the sample mean memory scores before and after a meal for these 10 people who were part of the study differ from each other. There is a 5% chance that the population mean memory score is the same before and after a meal. If the population mean memory score before a meal is the same as the population mean memory score after a meal and if another 10 people are given a memory test before and after a meal, then there would be a 5% chance that we would end up falsely concuding that the population mean memory score before a meal is lower than the population mean memory score after a meal O There is a 5% chance that your memory is so bad that you have already forgotten what this chapter is about.

Is memory ability before a meal worse 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 a Meal 61 72 63 58 78 77 58 67 77 67 After a Meal 60 62 68 71 78 71 71 74 75 69 Assume a Normal distribution. What can be concluded at the the a = 0.05 level of significance? For this study, we should use Select an answer a. The null and alternative hypotheses would be: Ho Select an answer Select an answer v Select an answer V(please enter a decimal) H Select an answer V Select an answer v Select an answer v (Please enter a decimal) b. The test statistic ?v (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 e. Based on this, we should Select an answer vthe null hypothesis. f. Thus, the final conclusion is that . O The results are statistically insignificant at a= 0.05, so there is insufficient evidence to conclude that the population mean memory score before a meal is lower than the population mean memory score after a meal, The results are statistically significant at a= 0.05, so there is sufficient evidence to conclude that the ten memory scores from the memory tests that were taken before a meal are lower on average than the ten memory scores from the memory tests that were taken after a meal. O The results are statistically significant at a = 0.05, so there is sufficient evidence to conclude that the population mean memory score before a meal is lower than the population mean memory score after a meal O The results are statistically insignificant at a = 0.05, 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.
