Do shoppers at the mall spend the same amount of money on average the day after Thanksgiving comparedto the day after Christmas? The 55 randomly surveyed shoppers on the day after Thanksgiving spent anaverage of $141. Their standard deviation was $47. The 52 randomly surveyed shoppers on the day afterChristmas spent an average of $167. Their standard deviation was Ş50. What can be concluded at the a =0.10 level of significance?For this study, we should use Select an answera. The null and alternative hypotheses would be:Ho: Select an answerSelect an answer vSelect an answer vH1: Select an answerSelect an answerSelect an answerb. The test statistic ? v =(please show your answer to 3 decimal places.)c. The p-value =d. The p-value is ? vae. Based on this, we should Select an answer v the null hypothesis.f. Thus, the final conclusion is that ...(Please show your answer to 4 decimal places.)O The results are statistically significant at a = 0.10, so there is sufficient evidence to concludethat the population mean amount of money that day after Thanksgiving shoppers spend is adifferent amount of money compared to the population mean amount of money that day afterChristmas shoppers spend.O The results are statistically insignificant at a = 0.10, so there is insufficient evidence toconclude that the population mean amount of money that day after Thanksgiving shoppersspend is a different amount of money compared to the population mean amount of money thatday after Christmas shoppers spend.The results are statistically significant at a = 0.10, so there is sufficient evidence to concludethat the mean expenditure for the 55 day after Thanksgiving shoppers that were observed is adifferent amount of money compared to the mean expenditure for the 52 day after Christmasshoppers that were observed.OThe results are statistically insignificant at a = 0.10, so there is statistically significantevidence to conclude that the population mean amount of money that day after Thanksgivingshoppers spend is equal to the population mean amount of money that day after Christmasshoppers spend.

Parents of teenage boys often complain that auto insurance costs more, on average, for teenage boys than for teenage girls. A group of concerned parents examines a random sample of insurance bills. The mean annual cost for 36 teenage boys was $673. For 23 teenage girls, it was $559. From past years, it is known that the population standard deviation for each group is $180. Determine whether or not you believe that the mean cost for auto insurance for teenage boys is greater than that for teenage girls. Conduct a hypothesis test at the 5% significance level. State the distribution to use for the test. (Round your answers to two decimal places.) What is the test statistic? (If using the z distribution round your answer to two decimal places, and if using the t distribution round your answer to three decimal places.) What is the p-value? (Round your answer to four decimal places.) Indicate the correct decision ("reject" or "do not reject" the null hypothesis), the reason for it, and…
