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.

Listed in the accompanying data table are student evaluation
ratings of courses and professors, where a rating of 5 is for
"excellent." Assume that each sample is a simple random sample
obtained from a population with a normal distribution. a. Use the
93 course evaluations to construct a 99% confidence interval
estimate of the standard deviation of the population from which the
sample was obtained. b. Repeat part (a) using the 93 professor
evaluations. c. Compare the results from part...
