Do shoppers at the mall spend more money on average the day afterThanksgiving compared to the day after Christmas? The 58 randomly surveyed shoppers on the day after Thanksgiving spent an average of $146. Their standard deviation was $34. The 52 randomly surveyed shoppers on the day after Christmas spent an average of $143. Their standard deviation was $40. What can be concluded at theaa = 0.01 level of significance?For this study, we should use Select an answer t-test for the difference between two dependent population means z-test for a population proportion t-test for the difference between two independent population means t-test for a population mean z-test for the difference between two population proportions -The null and alternative hypotheses would be:H0:H0: Select an answer 1 p1 Select an answer = ? > < Select an answer p2 2 H1:H1: Select an answer 1 p1 Select an answer > < ? = Select an answer 2 p2 -The test statistic ? z t = (please show your answer to 3 decimal places.) -The p-value = (Please show your answer to 4 decimal places.) -The p-value is ? > = aa -Based on this, we should Select an answer reject accept fail to reject the null hypothesis. -Thus, the final conclusion is that … -The results are statistically significant at aa = 0.01, so there is sufficient evidence to conclude that the mean expenditure for the 58 day after Thanksgiving shoppers that were observed is more than the mean expenditure for the 52 day after Christmas shoppers that were observed. -The results are statistically insignificant at aa = 0.01, so there is statistically significant evidence to conclude that the population mean amount of money that day after Thanksgiving shoppers spend is equal to the population mean amount of money that day after Christmas shoppers spend. -The results are statistically significant at aa = 0.01, so there is sufficient evidence to conclude that the population mean amount of money that day after Thanksgiving shoppers spend is more than the population mean amount of money that day after Christmas shoppers spend. -The results are statistically insignificant at aa = 0.01, so there is insufficient evidence to conclude that the population mean amount of money that day after Thanksgiving shoppers spend is more than the population mean amount of money that day after Christmas shoppers spend.MathStatistics and Probability MATH 117
