Question

Quizplus · Accepted Answer

In tests of significance involving two sample proportions, the value of the population proportion is estimated from the sample proportions. This is because we are comparing two proportions from different samples to determine if they are significantly different from each other or if they come from the same population. The sample proportions provide an estimate of the population proportions that we can use in our statistical calculations. Therefore, Choice C is the best choice for this question.
