Did you finish reading that book? A randomized comparative study used adult volunteers. The researchers assigned 100 of the
adults to read a book of their choosing and they randomly assigned the remaining 120 adults to read a book that was selected by
the researchers. The researchers found that 58.0% of the adults that chose their own book finished it within a week and that 35%
of adults in the group that was assigned a book to read finished it within a week.
Construct and interpret a 95% confidence interval for the true difference in the proportion of adults like these that got to pick
their own book versus those that were assigned a book who would finish the book within a week.
STATE:
95% CI for
P1-P2

P1
the true
proportion
of adults like these who are allowed to choose their own book that finish the
book within one week and
P2=the true
one week.
