The average McDonald's restaurant generates $2.4 million in sales each year with a standard deviation of 0.4. Ian wants to know if the average sales generated by McDonald's restaurants in North Dakota is different than the worldwide average. He surveys 33 restaurants in North Dakota and finds the following data (in millions of dollars): 2.4, 2.7, 2.9, 2.9, 2.2, 2.2, 2.2, 2.6, 1.9, 2.6, 2.5, 2.5, 2.1, 2.7, 2.9, 2.4, 2.2, 2.9, 2.3, 2.5, 2.2, 2.2, 2, 2, 2.4, 2.2, 2.4, 3, 2.9, 2.5, 2.2, 1.9, 2.1 Perform a hypothesis test using a 5% level of significance. Step 1: State the null and alternative hypotheses. Ho: ?? H₂: ? (So we will be performing a Select an answer test.)
