We can verify that a sampling distribution is normal using the Large Counts Condition, which states that we have at least 10 expected successes and 10 expected failures.The z-test is a statistical test for comparing the proportions from two populations. It can be used when the samples are independent, n1ˆp1 ≥ 10, n1ˆq1 ≥ 10, n2ˆp2 ≥ 10, and n2ˆq2 ≥ 10. The formula for the z-test statistic is: z = (ˆp1 − ˆp2) − (p1 − p2) √(ˆp ⋅ ˆq( 1 n1 + 1 n2))The conditions we need for inference on a mean are: Random: A random sample or randomized experiment should be used to obtain the data.

This is true if our parent population is normal or if our sample is reasonably large ( n ≥ 30) ‍.The Course at a Glance provides. useful visual organization of the AP Statistics curricular components, including: Sequence of units, along with approximate weighting and suggested pacing.
