You want to conduct a study on the proportion of Penn State students who miss class when it is
raining. Suppose here is the data you collect for students who live on-campus versus students
who live off-campus:
Never Miss Sometimes Miss Always Miss
On-Campus

a. For on-campus students (only), estimate the true difference in proportions for those who
never miss class versus those who always miss class, when it is raining. Place a bound on the
error of estimation.
b. Estimate the true difference between the proportions of on-campus students who always
miss class versus the proportion of off-campus students who always miss class, when it is
raining. Place a bound on the error of estimation.
