A data set about speed dating includes "like" ratings of male dates made by the female dates. The summary statistics are n= 189, x = 6.88, s = 2.06. 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? VA. Ha: = 7.00 O B. Ho: u= 7.00 H,: u> 7.00 H1: u<7.00 O C. Ho: H= 7.00 O D. Ho: u<7.00 H,: u#7.00 H: u>7.00 Determine the test statistic. - 0.80 (Round to two decimal places as needed.) Determine the P-value. O(Round to three decimal places as needed.)
