Suppose we now want to conduct hypothesis tests to see if the population mean order size is different than what we think it is. Use the orders-test holiday toys data set as before. Now we are going to use the template provided in the data set. Let's assume that we think if the average order size has changed it will be different from than 40 . This is our alternative hypothesis (Ha). Also, let's say that we would like a probability of Type l error to be alpha =.01 Ho: HaMu=40
