Anna's project for her introductory statistics course was to compare the selling prices of textbooks at two Internet bookstores. She first took a random sample of ten textbooks used that term in courses at her college, based on the list of texts compiled by the college bookstore. The prices of those textbooks at the two Internet sites are shown below. Perform a significance test comparing the population mean prices. Site A $115 $79 $41 $135 $99 $33 $81 $97 $117 $69 Site B $110 $79 $38 $129 $99 $33 $69 $97 $107 $66 Let ud be the population mean difference in price. State the hypotheses to test whether the mean price is lower at one of the two Internet bookstores. Choose the correct answer below. A. Ho: Hd = 0 and Ha: Hd 0 Determine the test statistic. t= 2.830 (Round to three decimal places as needed.) Determine the P-value. P-value = 0.020 (Round to three decimal places as needed.) Interpret the P-value in the context of the problem, using a significance level of 0.10. A. Since the P-value is greater than or equal to 0.10, there is insufficient evidence to suggest that the mean price is lower at one of the two Internet bookstores. O B. Since the P-value is greater than or equal to 0.10, there is sufficient evidence to suggest that the mean price is lower at one of the two Internet bookstores. C. Since the P-value is less than 0.10, there is insufficient evidence to suggest that the mean price is lower at one of the two Internet bookstores. D. Since the P-value is less than 0.10, there is sufficient evidence to suggest that the mean price is lower at one of the two Internet bookstores.Anna's project for her introductory statistics course was to compare the selling prices of textbooks at two Internet bookstores.
