A data set about speed dating includes "like" ratings of male dates made by the female dates. The summary statistics are n=188, x=5.56, s=1.81. 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. =< Determine the test statistic. (round to two decimal places as needed) Determine the P-value. (round to three decimal places as needed) State the final conclusion that addresses the original claim. (reject/fail to reject) H0. There is (not sufficient/sufficient) evidence to conclude that the mean of the population of ratings is (less than/more than) 6.00.

=<
Determine the test statistic.
(round to two decimal places as needed)
Determine the P-value.
(round to three decimal places as needed)
State the final conclusion that addresses the original claim.
(reject/fail to reject) H0. There is (not sufficient/sufficient) evidence to conclude that the mean of the population of ratings is (less than/more than) 6.00.
