In a survey of statistics students at Hope College, two of
the questions asked were their current grade point average (GPA) and how many
classes they failed to attend during the past three weeks at the college. The
data can be found in the fi le Miss Class GPA. Letâ€™s explore whether or not
there is evidence of a strong association between these two variables.
a. State the appropriate null and alternative hypotheses.
b. Conduct a simulation analysis with 1,000 repetitions.
What is your p-value?
Â c. Summarize your conclusion from this simulation analysis.
If there is an association, describe if it is positive or negative in the
context of the study.
d. Can you conclude a cause and effect between missing class
and GPA? Why or why not?
