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 thesame as the sample mean memory score for the 10 people who took the test after a meal andif another 10 people are given a memory test before and after a meal then there would be a20.1% chance of concluding that the mean memory score for the 10 people who took the testbefore a meal is at least 2,1 points lower than the mean memory score for the 10 people whotook the test after a meal.Of the population mean nmemory score before a meal is the same as the population meanmemory score after a meal and if another 10 people are given a memory test before and aftera meal then there would be a 20.1% chance that the mean memory score for the 10 peoplewho took the test before a meal would be at least 2.1 points lower than the mean memoryscore 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 testbefore a meal is at least 2.1 points lower than the mean memory score for the 10 people whotook 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 meanmemory score after a meal and if another 10 people are given a memory test before and aftera meal, then there would be a 5% chance that we would end up falsely concuding that thesample mean memory scores before and after a meal for these 10 people who were part of thestudy differ from each other.There is a 5% chance that the population mean memory score is the same before and after ameal.If the population mean memory score before a meal is the same as the population meanmemory score after a meal and if another 10 people are given a memory test before and aftera meal, then there would be a 5% chance that we would end up falsely concuding that thepopulation mean memory score before a meal is lower than the population mean memory scoreafter a mealO There is a 5% chance that your memory is so bad that you have already forgotten what thischapter is about. Is memory ability before a meal worse than after a meal? Ten people were given memory tests before theirmeal and then again after their meal. The data is shown below. A higher score indicates a better memoryability.Score on the Memory TestBeforea Meal61 72 63 58 78 77 58 67 77 67Aftera Meal60 62 68 71 78 71 71 74 75 69Assume a Normal distribution.

Thus, the final conclusion is that .O The results are statistically insignificant at a= 0.05, so there is insufficient evidence toconclude that the population mean memory score before a meal is lower than the populationmean memory score after a meal,The results are statistically significant at a= 0.05, so there is sufficient evidence to concludethat the ten memory scores from the memory tests that were taken before a meal are loweron 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 concludethat the population mean memory score before a meal is lower than the population meanmemory score after a mealO The results are statistically insignificant at a = 0.05, so there is statistically significantevidence to conclude that the population mean memory score before a meal is equal to thepopulation mean memory score after a meal.

The independent variable is memory ability. There are ten people of sample drawn. We have to test whether memory ability before a meal worse than after a meal or not. This paired t-test with left-tailed.EXCEL (Data Analysis) Procedure: Step 1: In EXCEL sheet, enter Before a Meal in one column and enter After a Meal in one column. Step 2: In Data, select Data Analysis and choose t test: Paired Two-samples for Mean. Step 3: In Input Variable 1 Range: select Before a Meal. Step 4: In Input Variable 2 Range: select After a Meal. Step 5: Select Lables. Click Ok. EXCEL (Data Analysis) output: P-value = 0.2010.Thus the final conclusion is that… The results are statistically insignificant at = 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.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 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.There is a 5% chance that the population mean memory score is the same before and after a meal.
