Answer:
Percentage of students who scored greater than 700 = 97.72%
Step-by-step explanation:
We are given that the College Board originally scaled SAT scores so that the scores for each section were approximately normally distributed with a mean of 500 and a standard deviation of 100.
Let X = percentage of students who scored greater than 700.
Since, X ~ N()
The z probability is given by;
Z = ~ N(0,1) where,
= 500 and
= 100
So, P(percentage of students who scored greater than 700) = P(X > 700)
P(X > 700) = P( <
) = P(Z < 2) = 0.97725 or 97.72% Therefore, percentage of students who scored greater than 700 is 97.72%.
