Question 936413
We want the probability(P) such that P(X<42), we need to calculate the z-score for this probability
z-score = (X - mean) / standard deviation = (42 - 37.5) / 7.6 = 0.592105263
now we need to consult the z-tables to find the associated probability
P{X<42) = 0.7224 which is approx 72%
