Do shoppers at the mall spend the same amount of money on average the day after Thanksgiving compared to the day after Christmas? The 56 randomly surveyed shoppers on the day after Thanksgiving spent an average of $149. Their standard deviation was $26. The 56 randomly surveyed shoppers on the day after Christmas spent an average of $140. Their standard deviation was $44. What can be concluded at 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 Select an answer Select an answer H: Select an answer Select an answer Select an answer b. The test statistic?= c. The p-value= d. The p-value is a (please show your answer to 3 decimal places.) (Please show your answer to 4 decimal places.) e. Based on this, we should Select an answer f. Thus, the final conclusion is that ... the null hypothesis. The results are statistically insignificant at a = 0.01, so there is insufficient evidence to conclude that the population mean amount of money that day after Thanksgiving shoppers spend is a different amount of money compared to the population mean amount of money that day after Christmas shoppers spend. The results are statistically significant at a 0.01, so there is sufficient evidence to conclude that the population mean amount of money that day after Thanksgiving shoppers spend is a different amount of money compared to the population mean amount of money that day after Christmas shoppers spend. The results are statistically significant at a = 0.01, so there is sufficient evidence to conclude that the mean expenditure for the 56 day after Thanksgiving shoppers that were observed is a different amount of money compared to the mean expenditure for the 56 day after Christmas shoppers that were observed. The results are statistically insignificant at a = 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.
