Interpret the meaning of the p-value in (a). Choose the correct answer below.
O A. The p-value is the probability of obtaining a sample mean difference less extreme than this one if the population mean prices at the two stores are different.
O B. The p-value is the probability of obtaining a sample mean difference at least as extreme as this one if the population mean prices at the two stores are the same.
OC. The p-value is the probability of failing to reject the null hypothesis when it is actually false.
d. Construct a 90% confidence interval estimate of the difference in the mean prices between the two stores.
The 90% confidence interval estimate isSHDS
