Similarly, if researcher fails to prove alternative hypothesis (or simply does nothing), then null hypothesis is assumed to be 2: set the decision decision-making criteria have to be based on certain parameters of datasets and this is where the connection to normal distribution comes into the per the standard statistics postulate about sampling distribution, “for any sample size n, the sampling distribution of x̅ is normal if the population x from which the sample is drawn is normally distributed.

If we find any calculations that go beyond the usual 2 standard deviations, then we have a strong case of outliers to reject the null hypothesis. Each high school will need to determine the length of time for its ap statistics course to best serve the needs of its students.
