In hypothesis tests about p₁ - p₂, the pooled estimator of p is a(n) A) simple average of and . B) weighted average of and . C) geometric average of and . D) exponential average of and .

Question

Quizplus · Accepted Answer

In hypothesis testing about the difference in proportions, the pooled estimator of p is a weighted average of the sample proportions from each group, where the weights are based on the sample sizes of each group. Therefore, choice B - weighted average of the two sample proportions - is the best choice for the pooled estimator of p. The other options (simple average, geometric average, and exponential average) do not accurately reflect the weighting of the sample proportions.
