A data set about speed dating includes​ "like" ratings of male dates made by the female dates. The summary statistics are n=196​, x=6.89​, s=1.92. 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.
