Wal-Mart wants to introduce a new subscription service (called Plum) that would result in customers getting free two-day delivery. Wal-Mart introduces Wal-Mart Plum to a random sample of 99 customers. You are hired by Wal-Mart to analyze if the introduction of Plum andtwo-day delivery increases sales for Wal-Mart. You find that the 99 random customers that were offered Plum Two Day Delivery spent $2,500 per year on Wal-Mart with a sample standard deviation of $500 in sales. (A) Test whether the sales of Wal-Mart Plum are statistically different from zero at an alpha of 1% (99% confidence level). Set up your null and alternative hypotheses. Test at the 1% level of significance. Show your test and critical statistics. Are the sales for Two-Hour Plum Delivery statistically different from 0? Interpret your answer.

A matched pairs experiment compares the taste of instant coffee with fresh-brewed coffee. Each subject tastes two unmarked cups of coffee, one of each type, in random order and states which he or she prefers. Of the 50 subjects who participate in the study, 19 prefer the instant coffee and the other 31 prefer fresh-brewed. Let p be the proportion of the population that prefers fresh-brewed coffee. a. Test the claim that a majority of people prefer the taste of fresh-brewed coffee. Report the z test-statistic and its p-value. Is your test result significant at the α = 10% level? What is your practical conclusion? b. compute the hypothesis testing with significance level a=10%. Use the data set above. c. Find a 95%(not 90%) confidence interval for population proportion p. Solution: Population: {Xi = 1} → Customer i prefers fresh-brewed coffee to instant coffee p = the proportion of the population that prefers fresh-brewed coffee. Hypotheses (UPPER, LOWER, or TWO-Tailed TEST) with ? =…
