Answer:
The proportion of scores reported as 1600 is 0.0032
Step-by-step explanation:
Let X be the score for 1 random person in SAT combining maths and reading. X has distribution approximately N(μ = 1011,σ = 216).
In order to make computations, we standarize X to obtain a random variable W with distribution approximately N(0,1)

The values of the cummulative distribution function of the standard Normal random variable, lets denote it
are tabulated, you can find those values in the attached file. Now, we are ready to compute the probability of X being bigger than 1600

Hence, the proportion of scores reported as 1600 is 0.0032.
