Question

Which is cheaper: eating out or dining in? The mean cost of a 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 comparable restaurant meal.

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, at α = .05, what is your conclusion?
