Listed below are attractiveness ratings made by participants in
a speed dating session. Each attribute rating is the sum of the
ratings of five attributes (sincerity, intelligence, fun, ambition,
shared interests).
Use a 0.05 significance level to test the claim that there is a
difference between female attractiveness ratings and male
attractiveness rating by following the steps below:
(a) State the null and alternative hypotheses, indicate the
significance level and the type of test (left-, right-, or
two-tailed test).

In a study of speed dating, male subjects were asked to rate the attractiveness of their female dates, and the sample of the results is listed below (1=not attractive; 10=extremely attractive). Construct a confidence interval using a 90% confidence level.
5, 9, 1, 8, 4, 5, 8, 8, 7, 8, 5, 9

A data set about speed dating includes "like" ratings of male dates made by the female dates. The summary statistics are n= 195, x= 5.88, s= 2.06. Use a 0.05 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.
