A data set about speed dating includes "like" ratings of male dates made by the female dates. The summary statistics are nequals=191191, x overbarxequals=7.597.59, sequals=2.022.02. Use a 0.050.05 significance level to test the claim that the population mean of such ratings is less than 8.008.00. 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.
