You survey 100 UWEC students about whether they prefer to shower
in the morning or in the evening, and find 67 who prefer the
morning. Based on this, you use the One Proportion
applet to do a series of two-sided hypothesis tests
?0:?=?0H0:π=p0
??:?≠?0Ha:π≠p0
for different proportions ?0. You find the following
p-values:

Data, Software Required):
There are two sections of statistics, one in the afternoon (PM)
with 30 students and one in the morning (AM) with 22 students. Each
section takes the identical test. The PM section, on average,
scored higher than the AM section. The scores from each section are
given in the table below. Test the claim that the PM section did
significantly better than the AM section, i.e., is...

A physiological experiment was concluded to study the effect of
various factors on a pulse rate. The participants took their own
pulse. They then were asked to flip a coin. If their coin came up
head, they were to run in place for 1 minute. Then everyone took
their own pulse again. The dataset pulse.txt, available from
Moodle, contains the following variables: ROW- id numbers, from 1
to 92; PULSE1- first pulse rate; PULSE2- second pulse rate;
RAN-1=ran in place,...
