A data set about speed dating includes "like" ratings of male dates made by the female dates. The summary statistics are n = 188, x= 5.89, s= 1.96. Use a 0.01 significance level to test the claim that the population mean of such ratings is lessthan 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. Ho: H= 6.00H1: µ<6.00B. H: μ<6.00H1: µ> 6.00O C. Ho: H= 6.00H1: µ> 6.00D. Ho: H= 6.00H4:µ#6.00Determine the test statistic.- 0.77 (Round to two decimal places as needed.)Determine the P-value.(Round to three decimal places as needed.)
