In this exercise, as in the one before, we eliminate
elections with more than two major party candidates as well as elections with
two candidates of the same height. In addition, we eliminate the two elections
in which George Washington was unopposed and five elections with missing data.
Consider four different data sets:
A. Elections from 1960 (Kennedy) to the present:
Â n = 14, pË† = 814 = 0.5714.
Â B. Elections from Theodore Roosevelt (1904) to the present:
Â n = 25, pË† = 1925 = 0.76.
Â C. Elections from John Adams (1796) through William
Â n = 16, pË† = 516 = 0.3125.
Â D. Elections from John Adams (1796) to the present:
Â n = 41, pË† = 2441 = 0.5854.
a.Â Â Â Â Â Â
The four p-values, from smallest to largest, are 0.007, 0.174, 0.395,
0.961. Match each data set (Aâ€“D) with its p-value.
b. What do you conclude about the
hypothesis that taller candidates are more likely to win?
