Draw frequency polygons for each of the four distributions, Ask an Expert

Statistics

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, find out 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
