A data set about speed dating includes "like" ratings of male dates made by the female dates. The summary statistics are n= 195, x= 5.88, s= 2.06. Use a 0.05 significance level to test the claim that the population mean of such ratings is less than 6.00. 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.

Listed below are attractiveness ratings made by participants in
a speed dating session. Each attribute rating is the sum of the
ratings of five attributes (sincerity, intelligence, fun, ambition,
shared interests).

difference between female attractiveness ratings and male
attractiveness rating by following the steps below:
(a) State the null and alternative hypotheses, indicate the
significance level and the type of test (left-, right-, or
two-tailed test).

13) For 50 randomly selected speed dates, attractiveness
ratings by males of their female date partners (x) are recorded
along with the attractiveness ratings by females of their male date
partners (y); the ratings range from 1 to 10. The 50 paired
ratings yield: x overbar=6.3, y overbar=6.2 , r=−0.220,
P-value=0.1250, and y^=7.79-0.248x. Find the best
predicted value of y^ (attractiveness rating by female of male)
