This assignment is about transforming statistics into Z-scores (and soon t-scores), and then calculating the probability of being above or below that score, or between two scores.

Now answer this question

Think of the growth charts when you went to the doctor as a child. What percentile were you in? What percent of your age group were below you or above you? What percent were between you and the average?These are the types of calculations we need to do with Z-(or t-)scores. We willtranslate anyvalue into its distance from the mean, plus or minus, and then we can say what percentile it is. 50% will be below the mean, and 50% above in our normal curves.
