According to The Vancouver Sun (December 18, 2010) McDonald's chicken fajita is labeled as having 6 grams of fat on average with a standard deviation of 1.2 grams. They did a sample of 3 fajitas, and found the average to be 10.76 grams of fat. Assuming normality, test at the 5% significance level if the McDonald's fajita has more fat than the label says. Show all the steps of a hypothesis test.
