A statistic is called an unbiased estimator of a parameter if the mean of its sampling distribution is equal to the parameter being estimated . Important Concepts for unbiased estimators. The mean of a sampling distribution will always equal the mean of the population for any sample size.Lesson 9.1 - Chi-Square Test for Goodness of Fit. Relevant Topics Covered.

So when we get to the formula for SD, it does not make sense to use different values (p1hat and p2hat) because we are assuming the two proportions are equal. Therefore we should be plugging in the same value for p1 and p2 in the formula for SD.AP Statistics Chapter 7 Multiple Choice Questions. 6 terms. Jordyn_Vu. Preview.

When you do a confidence interval problem, shade the area that we believe the true parameter is in. Color the tails in a different color to make the students see the region a two-sided hypothesis test is assessing. Therefore - a 90% confidence interval would have 10% leftover in the tails - or 5% on each side.
