A restaurant association says the typical household in the United States spends a mean amount of $2628 per year on food away from home. You are a consumer reporter for a national publication and want to test this claim. A random sample of 34 U.S. households has a mean amount spent on food away from home of $2694 and a standard deviation of $322. At α = 0.05, do you have enough evidence to reject the association’s claim?
(a) Identify the claim and state H0 and Ha,
(b) Use technology to find the P-value,
(c) Decide whether to reject or fail to reject the null hypothesis,
(d) Interpret the decision in the context of the original claim. Assume the population is normally distributed. |
