(13points) An airline wants to learn about three different bonus plans and their corresponding customer's satisfaction. Specifically, they want to test if plan A, plan B, and plan C are equal in satisfaction scores. They took a sample from customers of each plan, and used aov function in R. The results showed that the error within each plan is 2 (MSE = 2), and the error between plans is 3 (MSTR = 3). If the F critical value is 4, write a null and alternative hypothesis and test if the average training time is equal in all four plans.(13points) An airline wants to learn about three different bonus plans and their corresponding customer's satisfaction.
