since x (mean) is equal to 58 and the standard deviation is equal to 6-
x-s=52
x+s=64
x-2s=46
x+2s=76
x-3s=40
x+3s=76
therefore 64 is 1 (one) standard deviation above the mean from x+s, so 50%+34%(one standard deviation above)= 84%
the mean is the central line on the normal...
Percentage of students who scored less than 64=50%+34%
=84%
therefore 84% of 150 students is equal to (84/100)x150=126
126 students would have scored less than 64
