An investigator theorizes that people who participate in a
regular program of exercise will have levels of systolic blood
pressure that are significantly different from that of people who
do not participate in a regular program of exercise. To test this
idea the investigator randomly assigns 40 subjects to an exercise
program for 10 weeks and 40 subjects to a non-exercise comparison
group. After ten weeks the mean systolic blood pressure of subjects
in the exercise group is 137 and...

Research indicates that people who volunteer to
participate in research studies tend to be natives of the general
area more than non-volunteers. To test this phenomenon, a
researcher obtained a sample of 275 Pierce college students. The
students were given a description of a psychological research study
and asked whether they would volunteer to participate. The
researcher also asked where they were from. Use a χ² square to
determine if there is a significant relationship between being
local and volunteering....
