1. A slice of pizza in the college Cafe has a mean price of $2.75 with a standard deviation of $0.29. If you sample 15 days of pizza sales, what is a 99% confidence interval for the price of pizza?What is your value for E?What is your confidence interval?2. Six different national brands of chocolate chip cookies were randomly selected at the supermarket. The grams of fat per serving are as follows: 8; 8; 10; 7; 9; 9. Assume the underlying distribution is approximately normal. Find the 90% confidence interval for the mean number of grams of fat per serving. (Hint: Use Minitab to find the mean and standard deviation!)What is your value for E?What is your confidence interval?3. Stanford University conducted a study of whether running is healthy for men and women over age 50. During the first eight years of the study, 2.5% of the 625 members of the 50-Plus Fitness Association died. We are interested in the 99% confidence interval of the proportion of people over 50 who ran and died in the same eight-year period.
