Question

A data set about speed dating includes "like" ratings of male dates made by the female dates. The summary statistics are

n=198,

x=7.51,

s=1.86.

Use a 0.10 significance level to test the claim that the population mean of such ratings is less than 8.00.

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?

Determine the test statistic.

State the final conclusion that addresses the original claim.

(Reject or Fail to Reject) H0. There is (sufficient or insufficient) evidence to conclude that the mean of the population of ratings is (greater than or equal to or not or less than) 8.00.
