Sixty
percent
of 100
randomly selected
shoppers who were classified as having rural backgrounds said they
prefer to purchase camera equipment in discount stores. In a
comparable study involving 250 shoppers with urban backgrounds, 50
percent said they would prefer the discount stores. At the 1%
significance level, is there a difference between the two groups in
the proportion who prefer discount stores?

Are medical students more motivated than law students?
A randomly selected group of each were administered a survey of
attitudes toward Life, which measures motivation for upward
mobility. The scores are summarized below. The researchers suggest
that there are occupational differences in mean testosterone level.
Medical doctors and university professors are two of the
occupational groups for which means and standard deviations are
recorded and listed in the following table.
