Restaurateur Denny Valentine is evaluating two sites, Raymondville and Rosenberg, for his next restaurant.Denny suspectsthat Raymondville residents (population 1) dine out more often (number of times per month) than Rosenberg residents (population 2). Denny commissions a market survey to test this hypothesis. The market researcher used a random sample of 64 families from each suburb, and recorded the number of times each population dines out. The market researcher finds that the sample difference in mean number of dine out times is 3.54 (population 1- population 2). The calculated two-tail p-value= 0.03. Assuminga= .02 (i.e., alpha = 0.02),the appropriate decision is _________________.
