Scores on the math portion of the SAT (SAT-M) in a recent year have followed a normal distribution with mean μ = 507 and standard deviation σ = 111. What is the probability that the mean SAT-M score of a random sample of 4 students who took the test that year is more than 600? If normality conditions are met, round your Z-score calculation to 2 decimal places. Normal Distribution Calculator (Standard Normal) Group of answer choices 1. P(Z>1.68) =...

Scores on the math portion of the SAT (SAT-M) in a recent year have followed a normal distribution with mean μ = 507 and standard deviation σ = 111. What is the probability that the mean SAT-M score of a random sample of 4 students who took the test that year is more than 600? Explain why you can solve this problem, even though the sample size (n = 4) is very low.
