The manager of Frenchies is concerned that patrons are not consistently receiving the same amount of French fries with each order. The chef claims that the standard deviation for a 7-ounce order of fries is at most 0.8 ounces. To test the chef's claim, the manager randomly weighs 28 orders of fries with the following results (in ounces): 7.7, 5, 7.3, 8.7,7.8, 8.3, 8.3, 6.2, 6.1, 7.8, 6.3, 6.9, 4.8, 7.4, 6, 7.2, 6.5, 7, 7.9, 8.7, 7.9, 7.1, 5.7, 7.1, 8.4, 6.8, 6.3, 6.3 Perform a hypothesis test using a 2% level of significance to test the chef's claim. Step 1: State the null and alternative hypotheses. Ho:o sv 0.8 Ha:o >v 0.8 (So we will be performing a right-tailed v test.)

The average McDonald's restaurant generates $3.6 million in sales each year with a standard deviation of 0.9. Trent wants to know if the average sales generated by McDonald's restaurants in Kentucky is different than the worldwide average. He surveys 27 restaurants in Kentucky and finds the following data (in millions of dollars): 4.1, 2.8, 4.4, 4.5, 5.3, 5, 3.7, 2.9, 3.8, 4.8, 3.6, 2.3, 3.7, 2.9, 2.9, 4, 1.1, 5.2, 2.9, 5, 4, 4, 5.9, 3.2, 2.2, 4.3, 3.8 Perform a hypothesis test using a 3% level of significance. Step 1: State the null and alternative hypotheses. Ho: [? v] ? v На: ? ? v (So we will be performing a Select an answer 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.
