Question

You and a friend are going golfing. When you hit the golf ball, the distance the ball travels can be modeled by a normal distribution with a mean of 150 yards and a standard deviation of 8 yards. Identify the following z-scores.

#Round to 2 decimal places!
The z-score for hitting the golf ball 170 yards is
The z-score for hitting the golf ball 90 yards is

Answer 1

z = (170 - 150)/8 = 20/8 = 2.5

z = (90 - 150)/8 = -60/8 = -7.5
