A restaurant association says the typical household in the United States spends a mean amount of $2698 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 28 U.S households has a mean amount spent on food away from home of $2764 and a standard deviation $322. At α=0.05, do you have enough evidence to reject the association's claim?

A restaurant association says the typical household in the U.S. spends a mean amount of more than $2628 per year on food eaten away from home. You are a consumer reporter and wish to test this claim. A random sample of 36 U.S. households has a mean amount spent away from home of $2713 with a standard deviation of $322. Perform the appropriate hypothesis test at α = 0.05. Note: Round your data to at least 3 decimal places.

The American Restaurant Association collected information on the number of meals eaten outside the home per week by young married couples. A survey of 60 couples showed the sample mean number of meals eaten outside the home was 2.76 meals per week, with a standard deviation of 0.75 meal per week. Construct a 99% confidence interval for the population mean. Please consider the standard deviation a population statistic.
