Suppose we have independent random samples of size n 1 = 420 and n2 = 510. The proportions of success
in the two samples are p1= .38 and p2 = .43. Find the 99% confidence interval for the difference in the
two population proportions.
, Answer the following questions:
1. Multiple choice: Which equation would you use to solve this problem?
A.
B.
C.
D.
2. List the values you would insert into that equation.
3. State the final answer to the problem
Your Answer:
1. The answer is B.
2. The values listed are: n1=420, n2=510, p1=.38, p2=.43, and 99% confidence relate to z=2.58, sample
size is greater than 30.
3. When using the formula above (B):
Therefore the interval will be : .-0.1333,-0.03326
From table 6.1, we see that 99% confidence corresponds to z=2.58. Notice that the sample sizes are
each greater than 30, so we may use eqn. 8.2:
