Question

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 $12.60 and a standard deviation of $2 for a comparable restaurant meal.

(a)	Choose the 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.
	H0: - Select your answer from -(µ > 13.04 or µ ≤ 13.04 or µ < 13.04 or µ ≥ 13.04 Ha: - Select your answer from -µ > 13.04 or µ ≤ 13.04 or µ < 13.04 or µ ≥ 13.04
(b)	Using the sample from the 100 restaurants, what is the p value? If required, round your answer to four decimal places.
(c)	At α = 0.05, what is your conclusion?
	We -(reject or fail to reject)- the null hypothesis. We -(can or cannot)- conclude that the cost of a restaurant meal is significantly cheaper than a comparable meal fixed at home.
