Arbitron Media Research Inc. conducted a study of the iPod listening habits of men and women. One facet of the study involved the mean listening time. It was discovered that the mean listening time for a sample of 13 men was 40 minutes per day. The standard deviation was 11 minutes per day. The mean listening time for a sample of 12 women was also 40 minutes, but the standard deviation of the sample was 17 minutes. At the 0.02 significance level, can we conclude that there is a difference in the variation in the listening times for men and women? (Round your answer to 3 decimal places.)

a. According to a study conducted for Gateway Computers, 60% of
men and 70% of women say that weight is an extremely/very important
factor in purchasing a laptop computer. Suppose this survey was
conducted using 374 men and 481 women. Do these data show enough
evidence to declare that a significantly higher proportion of women
than men believe that weight is an extremely/very important factor
in purchasing a laptop computer? Use a 5% level of significance. b.

A university conducted a study of whether running is healthy
for men and women over age 50. During the first eight years of the
study, 1.9% of the 457 members of a fitness association died. We
are interested in the proportion of people over 50 who ran and died
in the same eight-year period.
NOTE: If you are using a Student's t-distribution, you may
assume that the underlying population is normally distributed. (In
general, you must first prove that assumption,...
