A random sample of 36 orders at a fast food restaurant was studied to determine the amount of the order. The results had a mean of $15.50 with a standard deviation of $8.98. An article in the local paper claims that the average amount spent in a visit to the fast-food restaurant is less than $20. Is there significant evidence that the mean amount of orders at the fast foom restaurant is less than $20 at a 5% significance level? Use the P-value method to run the hypothesis test. Show all steps. 1.) Identify the null and alternative hypotheses. Enter»,<,>, or "not equal" for Ho: Hy:
