State and check the Random, 10%, and Large Counts conditions for a chi-square test based on data in a two-way table.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.

Normal: The sampling distribution of x ¯. ‍. (the sample mean) needs to be approximately normal. This is true if our parent population is normal or if our sample is reasonably large ( n ≥ 30) ‍.The large counts condition can be expressed as np ≥ 10 and n (1-p) ≥ 10, where n is the sample size and p is the sample proportion. This means that both the number of successes (np) and the number of failures (n (1-p)) in the sample should be at least 10.
