Question

The SAT mathematics scores in the state of Florida are approximately normally distributed with a mean of 500 and a standard deviation of 100

Using the empirical rule, what is the probability that a randomly selected student's math score is between 300 and 700? Express your answer
as a decimal

Answer 1

0.9545

Explanation:

Use a calculator with probability distribution functions.

Here we'd use normcdf( ).

normcdf(300,700,500,100) = approximately 0.9545
