A data set about speed dating includes "like" ratings of male
dates made by the female dates. The summary statistics are n=194,
x overbar=6.81, s=1.91. Use a 0.05 significance level to test the
claim that the population mean of such ratings is less than 7.00.
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?...
