1. 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).
-
(b) Calculate by hand the test statistic.
-
(c) Use the appropriate sheet in the Hypothesis Test and Confidence Interval template to complete all relevant computations (including the test statistic: compare with (b) to confirm your calculation is correct). Add a screenshot.
-
(d) Use the P-value obtained in (c) to explain whether or not the null hypothesis is rejected.
-
(e) Make a concluding statement.
-
(f) Comment on potential issues related to the validation of your result (Hint: the sub-
jective nature of the measures)

The accompanying table lists the "attribute" ratings made by a
random sample of 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 attribute ratings and male attribute
ratings.

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
What is the confidence interval for the population mean?

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.
