The average Mcdonald's restaurant generates $2.2 million in sales each year with a standard deviation of 0.7. Derek wants to know if the average sales generated by Mcdonald's restaurants in New Jersey is different than the worldwide average. He surveys 21 restaurants in New Jersey and finds the following data (in millions of dollars): 2.5, 2.3, 2.2, 0.2, 1.4, 2.1, 1.6, 1, 1.9, 2.4, 2.7, 1.8, 3.4, 2.6, 1.7, 1.1, 1.5, 0.3, 2.9, 1.2, 1.1 Perform a hypothesis test using a 7% level of significance. Step 1: State the null and alternative hypotheses. Ho: ? v ?v Ha: 2 v ?v (So we will be performing a Select an answer v | test.) Step 2: Assuming the null hypothesis is true, determine the features of the distribution of point estimates using the Central Limit Theorem. By the Central Limit Theorem, we know that the point estimates are Select an answer v with distribution mean and distribution standard deviation Step 3: Find the p-value of the point estimate. P-value Step 4: Make a Conclusion About the null hypothesis. Since the P-value = ? V Q, we Select an answer v the null hypothesis. We cannot conclude that the mean sales of Mcdonald's restaurants in New Jersey differ from average Mcdonald's sales worldwide. We conclude that the mean sales of Mcdonald's restaurants in New Jersey differ from average Mcdonald's sales worldwide
