The average McDonald's restaurant generates $3.6 million in sales each year with a standard deviation of 0.9. Erik wants to know if the average sales generated by McDonald's restaurants in Idaho is different than the worldwide average. He surveys 27 restaurants in Idaho and finds the following data (in millions of dollars): 4, 2.3, 4.9, 1.5, 3, 3.6, 4.1, 4.2, 4.4, 4, 4.5, 3.5, 4.1, 4.5, 3.4, 3.4, 4.1, 3.8, 3, 2.9, 3.1, 4.3, 3.7, 3.1, 2.9, 4.5, 5.1 Perform a hypothesis test using a 1% level of significance.
