The 53 randomly surveyed shoppers on the day after Thanksgiving spent an average of $136. Their standard deviation was $38. The 50 randomly surveyed shoppers on the day after Christmas spent an average of $137. Their standard deviation was $47. 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 H₁: Select an answer Select an answer Select an answer b. The test statistic ? = c. The p-value = d. The p-value is ? a e. Based on this, we should f. Thus, the final conclusion is that ... Select an answer Select an answer ◊ (please show your answer to 3 decimal places.) (Please show your answer to 4 decimal places.) Select an answer the null hypothesis. O 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. O 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 less than the population mean amount of money that day after Christmas shoppers spend. O The results are statistically significant at a = 0.01, so there is sufficient evidence to conclude that the mean expenditure for the 53 day after Thanksgiving shoppers that were observed is less than the mean expenditure for the 50 day after Christmas shoppers that were observed. O 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 less than the population mean amount of money that day after Christmas shoppers spend.
