A data set about speed dating includes "like" ratings of male dates made by the female dates. The summary statistics are n=198, x̅=6.51, s=1.87 . 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.
