3. Assume that SAT math scores approximate a normal curve with amean of 300 and a standard deviation of 55 A) Sketch a normal curveand shade in the target area(s) described by each of the followingstatements
A5) More than 75 points above mean
A6) More than 95 points either above or below the mean
A7) Within 80 points either above or below the mean
B)Plan solutions ( in term of columns B,C, B’, and C’) for thetarget areas in part (a)
C)Convert to zcores and find the target areas in part (a)
