Suppose that, on average, U.S. adults get fast food 10 times a week. In a random sample of 41 people, it was found that they ordered fast food an average of 9 times in one week. Assume the population standard deviation is 4.4. Perform a test at a significance level of 5% to determine whether or not the number of times a U.S. adult gets fast food in a week is different from 10.
