Answer: D. A confidence interval is used to test a claim about two population proportions.

Explanation: Confident interval estimate is a type of estimate computed from statistics of observed data.

The confident interval estimate of the difference between two population proportions will use a standard deviation based on estimated values of the population proportion. The confident interval will be used to estimate the difference in the two population proportions, but it will not be used to test claim about two population proportions because it can not.
