A data set about speed dating includes "like" ratings of male dates made by the female dates. The summary statistics are n = 189, x= 6.58, s = 2.07. 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 The p-value? Reject H0 if the P-value is less than or equal to the significance level a. Fail to reject H0 if the P-value is greater than a.
