Answer:
0.658 is the probability that a sample 90 test takers will provide a sample mean test score within 10 points of the population mean of 502. 
Step-by-step explanation:
The following information is missing:
The standard deviation of population is 100.
We are given the following information in the question:
Population mean, μ = 502
Standard Deviation, σ = 100
Sample size, n  = 90
Standard error = 

Formula:

P(test score within 10 points)


0.658 is the probability that a sample 90 test takers will provide a sample mean test score within 10 points of the population mean of 502.
