Find the probability that an individual’s SAT score is greater than 650 (Hint: find the probability for “less than 650” first).
Find the standard values (z-score) for students scoring 540, 600, 650, 700 on the test. Explain what this means.
Hint: use the function =NORM.DIST(X, mean, STD, 1). X=600 Hint: z-score= (observation-mean)/standard deviation
