A data set about speed dating includes "like" ratings of male dates made by the female dates. The summary statistics are n=184, x=5.55, s=1.85. Use a 0.01 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? A. H0: μ<6.00 H1: μ>6.00 B. H0: μ=6.00 H1: μ≠6.00 C. H0: μ=6.00 H1: μ<6.00 D. H0: μ=6.00 H1: μ>6.00 Determine the test statistic. ________ (Round to two decimal places as needed.) Determine the P-value.

A data set about speed dating includes "like" ratings of male dates made by the female dates. The summary statistics are n=184, x=5.55, s=1.85.
Use a 0.01 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.
