X=21
EFG=3×21-20
=63-20=43
Mean is and a standard deviation is , then the variable .
Use substitution
.
This substitution gives you that .
a. For X=130, and (the decimal value is taken from the Standard Normal Distribution Table).
b. For X=90, and for X=110, . Then (the decimal value is taken from the Standard Normal Distribution Table).
