Explain how we can use the normal distribution to test hypotheses about populations.
What will be an ideal response?
If we know that a population of scores is normally distributed, we can use z-scores and the unit normal table to determine how likely it is that a sample mean came from that population using its distribution of sample means. If it is a very uncommon score, then it probably did not come from that distribution (or population) and can help us determine if something we want to compare is different in some way. The next chapter will discuss this process and the steps for testing hypotheses in more detail.
