A data set about speed dating includes "like" ratings of male dates made by the female dates. The summary statistics are n = 189, x = 6.52, s = 1.95. 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. What are the null and alternative hypotheses? O A. Ho k<7.00 H₁: μ>7.00 O C. Ho u=7.00 H₁: μ>7.00 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. Ho. There is B. Ho k=7.00 H₁<7.00 OD. Ho=7.00 H₁: 7.00 evidence to conclude that the mean of the population of ratings is 7.00.
