Melina works on the campaign of a political candidate. She suspected that voters in district 1 were more likely to
support her candidate than voters in district 2. She obtained separate random samples of voters from each
district. Here are the results:
Supports candidate?
District 1
District 2
Yes
64
96
No
36
104
Total
100
200
Melina wants to use these results to construct a 90% confidence interval to estimate the difference in the
proportion of voters in these districts who support her candidate (p1 - pa). Assume that all of the conditions
for inference have been met.
Which of the following is a correct 90% confidence interval based on Melina's samples?
