For each of the following sets of data (represented by the mean and standard deviation below), identify the end-points for six standard deviation units (that is between +/- 3SD around the mean). Additionally, calculate the range from "mean-3SD" to "mean+3SD"). Draw frequency polygons for each of the four distributions (assume they are normal) with the raw scores indicated for all six of the standard deviation units.
a) Mean= 15 SD= 3 b) Mean= 1,000 SD= 250 c) Mean= 75 SD= 5 d) Mean= 150 SD= 15
