A data set about speed dating includes "like" ratings of male dates made by the female dates. The summary statistics are n=197, x=6.89, s=2.08. Use a 0.05 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. What are the null and alternative hypotheses? =< 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. (fail to reject/reject) H0. There is (sufficient/not sufficient) evidence to conclude that the mean of the population of ratings is (greater than/not/equal to/less than) 7.00.

What are the null and alternative hypotheses?
=<
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.
(fail to reject/reject) H0. There is (sufficient/not sufficient) evidence to conclude that the mean of the population of ratings is (greater than/not/equal to/less than) 7.00.
