Answer:
721.54
Step-by-step explanation:
We have to convert the 2% given in the statement into a z-score, as follows:
P (X> x) = 2% = 0.02, P (Z> z) = 0.02
thus find z such that:
P (Z <z) = 1 - P (Z> z)
P (Z <z) = 1 - 0.02
P (Z <z) = 0.98
we look for what value of z corresponds to in the normal distribution table and it is 2.06
x = m + z * sd
m is mean and sd standard deviation, replacing:
x = 497 + 2.06 * 109
x = 721.54
721.54 would be the minimum score.
