A cell phone's SAR (Specific Absorption Rate) is a measure of the amount of radio frequency (RF) energy absorbed by the body when using a cell phone.The rate can vary by the distance of the phone from the ear.Below is a table showing SAR (y) and distance (x) for a sample of five 10 minute calls. The slope of the least squares line is 59.6.The intercept is -12.Compute the "total variation" (SST).
A)432
B)202
C)316
D)520
E)164
