A data set about speed dating includes "like" ratings of male dates made by the female dates. The summary statistics are n=190, x=6.54, s=1.84. 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. a) What are the null alternative and alternative hypotheses? b) Determine the test statistic. c) Determine the P-value. d. (reject/fail to reject). There is (sufficient/not sufficient) evidence to conclude that the mean of the population of ratings is (=, not, <, >) 7.00
