31. Meal Costs. Which is cheaper: eating out or dining in? The mean cost of a flank steak, broccoli, and rice bought at the grocery store is $13.04. A sample of 100 neighborhood restaurants showed a mean price of $12.75 and a standard deviation of $2 for a compa- rable restaurant meal. a. Develop appropriate hypotheses for a test to determine whether the sample data support the conclusion that the mean cost of a restaurant meal is less than fixing a comparable meal at home. b. Using the sample from the 100 restaurants, what is the p value? c. At a = 0.05, what is your conclusion?
