Enter your answer as a percent accurate to 1 decimal place (do not enter the "%" sign). Answers obtained using exact z-scores or z-scores rounded to 3 decimal places are accepted.

Explanation / Answer

Given =1531,standard deviation=302

If X=595, Z=(595-1531)/302=-3.099.

P(X>595)=P(Z>-3.0993)=P(0<=Z<=3.0993)=49.9
