A data set about speed dating includes "like" ratings of male dates made by the female dates. The summary statistics are n= 195 , x=5.52, s= 1.87. Use a 0.10 significance level to test the claim that the population mean of such ratings is less than 6.00. 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 =6.00 H p>6.00 O B. Ho p<6.00 H: u>6.00 O C. Ho H=6.00 H u#6.00 O D. Ho =6.00 H, u<6.00 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 v 6.00 V evidence to conclude that the mean of the population of ratings is V Họ. There is
