This prevents students from trying to apply chi-square models to percentages or, worse, quantitative …In a two sample z-test for difference of proportions, we assume the null hypothesis is true (p1 = p2). 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 Probability FRQs. 67 terms. revenge75. Preview. Statistics Quiz 4. 18 terms. vivdb1031. Preview.
