The 50 paired ratings yield x overbar=6.3​, y overbar=5.9​, r=-0.169​, ​P-value=0.240​, and ModifyingAbove y with caret=7.18 -0.198x. Find the best predicted value of ModifyingAbove y with caret ​(attractiveness rating by female of​ male) for a date in which the attractiveness rating by the male of the female is xequals9. Use a 0.01 significance level.

A data set about speed dating includes​ "like" ratings of male dates made by the female dates. The summary statistics are n=198​, x overbar=6.86​, s=2.09. Use a 0.01 significance level to test the claim that the population mean of such ratings is less than 7.00. Assume that a simple random sample has been selected. Identify the null and alternative​ hypotheses, test​ statistic, P-value, and state the final conclusion that addresses the original claim.
