Answer to Problem 11E
The confidence interval is
Explanation of Solution
Given:
Conditions to be satisfied:
There are three conditions to be satisfied:
Random: It is satisfied because the samples are independent random samples.
Independent: It is satisfied because assuming that
Normal: It is satisfied because there are
Thus, all the conditions are satisfied.
Calculation:
The sample proportion is the number of successes divided by the sample size. Then, we have,
Now, for the confidence interval
Thus, the confidence interval will be:
Thus, we conclude that, we are
