(Do not need EXCEL for this question) The z score measures the position of a data point relative to the mean terms of the standard deviation. Specifically, z value of a measurement = ( measurement sample mean ) / ( standard deviation ) . When two measurements originate from different sources, converting them to the z scale helps us draw a sensible interpretation of their relative magnitudes. 4a. In a large biology class, John obtained 350 points. The class average is 490 with a standard deviation of 120. Express John's score as a z-score. Interpret John's z-score (in one or two sentences). 4b. In the same class, Jill obtained a z-score of 1.20 . What is Jill's raw (i.e., actual) score?
