Answer:
95%
Step-by-step explanation:
All you have to do is multiply both number by 5 and after you do that you should get 95/100 and then since we have the 100 as the denominator then we could take the numerator and then you can take it off and then you have you decimal.
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>
