\fb. What assumption is necessary about the population distribution in order to perform this test? 0 A. It must be assumed that the distribution of the differences between the prices is approximately uniform. O B. It must be assumed that the distribution of the differences between the prices is approximately normal. 0 C. It must be assumed that the distribution of the differences between the prices is skewed. c. Find the p-value in (a) and interpret its meaning. The test statistic gives a p-value of (Round to three decimal places as needed.) Interpret the meaning of the p-value in (a). Choose the correct answer below. 0 A. The p-value is the probability of obtaining a sample mean difference at least as extreme as this one if the population mean prices between the stores are the same. 0 B. The p-value is the probability of obtaining a sample mean difference less extreme than this one if the population mean prices between the stores are different. 0 C. The p-value is the probability of failing to reject the null hypothesis when it is actually false. \fThe price of 30 random foods were compared between two dierent superstore chains. The prices for the products are shown in the accompanying data table. Complete parts (a) through (c) below. a Click the icon to view the data table for the prices of the products. a. At the 0.10 level of signicance. is there evidence that the mean price of items is higher at store Athan at store B? Let p1 be the mean prices at store A and let [42 be the mean prices for store B. State the null and alternative hypotheses. Choose the correct answer below. 0 A. H0:pD=O (wherepD=p1-p2) O B. H0:pDSD (wherepD=p1-p2) H12pD0 H1:|,|D>O O C. Homoao (wherepD=p1-p2) O D.
