The author recorded actual temperatures (F) along with the temperatures (F) that were predicted five days earlier. Results are listed below. Test the claim that there is no mean difference in the actual temperatures and the predicted temperatures. Give the null and alternative hypothesis.

Date	9/1	9/5	9/12	9/15	9/22	9/23	9/27	9/30
Actual High	80	73	78	73	82	81	74	62
High forecast five Days Earlier	80	79	79	78	73	79	70	69
