Let X be the weekly incomes of a large group of executives. The weekly incomes of a large group of executives follows Normal distribution with mean $2000 and standard deviation $100.
μ =2000, σ =100

Z =
=
Z = 100/100
Z = 1
The z score for income $2100 is 1
Move all terms to the left side and set equal to zero. Then set each factor equal to zero.
x=10,−1
