A data set about speed dating includes "like" ratings of male dates made by the female dates. The summary statistics are nequals186, x overbarequals6.51, sequals1.83. 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? A. Upper H 0: muequals7.00 Upper H 1: munot equals7.00 B. Upper H 0: muequals7.00 Upper H 1: mugreater than7.00 C. Upper H 0: muequals7.00 Upper H 1: muless than7.00 Your answer is correct.D. Upper H 0: muless than7.00 Upper H 1: mugreater than7.00 Determine the test statistic. negative 3.65 (Round to two decimal places as needed.) Determine the P-value. 0 (Round to three decimal places as needed.) State the final conclusion that addresses the original claim. Fail to reject Upper H 0. There is not sufficient evidence to conclude that the mean
