In one study of smokers who tried to quit smoking with nicotine patch therapy, 30 were smoking after one
year of treatment while 65 were not. We are interested in the true proportion of those that were still
smoking after one year of treatment.
a) What parameter are we estimating? p
b) What is the point estimate of that parameter?
c) What is a success for this problem? still smoking
d) Find the margin of error for a 90% confidence interval, rounded to the 4th.

e) Round to the fourth.
We are 90% confident that the true proportion of those that were still smoking after one year of treatment
is between 0.228 X and 0.402 X
