can someone double check to see if i did this correctly and am i supposed to include the z-score

The average commute to work (one way) is u =22 minutes according to one study. Assume the variable is normally distributed with a standard deviation of o = 4.2 minutes, what is the probability that: a) a randomly selected commuter spends more than 25 minutes commuting one way? (draw the curve and shade the region) 25 - 22 Z = 4.2 22 25 =.714
