WebWe know that 170 is one standard deviation away from the mean: 170 - 150 = 20 In a z-table, look up the z-score 1.00 (my table gives me 0.84134). That is the probability P (H<170) since z-scores work toward the left. We want the opposite, P (H>170), so subtract that value from 1: 1 - 0.84134 = 0.15866, or roughly 16% I hope this helped.
