 Question Answer if a school has a GPA of 2.8 and a standard deviation of 0.8 what percent of students have a GPA less then 2? greater then 3? P(x< or equal to 2) = P(Z < -1) = 0.1587 P(x>3) = P(Z>0.25)=1-P(X< of equal to 0.25) = 1-0.5987 = 0.4013 between 2 and 3? - P(2 2000 pounds = X1 + x2 + ……….. x10 / 2 = 2000/10 = 200. the Z score for 200 is 3.16. 1-p(z < or equal to 3.16) = 0.9992 = 0.0081-p(z < or equal to 3.16) = 0.9992 = 0.008
