x-intercept(s): (1/2, 0) or (0.5, 0)
y-intercept(s): (0, −2)
To solve for the minimum score required, we find for the z
score value at P = 0.97 (top 3%). The z score is:
z = 1.88
Then we use the formula to find for X:
z = (X – u) / s
1.88 = (X – 400) / 100
X = 588
<span>You have to score at least 588.</span>
