A data set about speed dating includes "like" ratings of male dates made by the female dates. The summary statistics are n = 193, x = 7.52, s = 1.97. Use a 0.05 significance level to test the claim that the population mean of such ratings is less than 8.00. 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: HI = 8.00 O B. Ho: H 8.00 O C. Ho: H = 8.00 O D. Ho: H = 8.00 Hy : H > 8.00 Hy : u # 8.00 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 evidence to conclude that the mean of the population of ratings is 8.00
