Answer:
The z score is 1.57
Step-by-step explanation:
μ = 69.0, σ = 2.8 and x = 73.4
The objective of the problem is to obtain the z-score of a man 73.4 inches tall. The required z score is derived through the following formula "{x - μ / σ}"
z = 73.4 - 69.0 / 2.8
z = 4.4 / 2.8
z = 1.571428571428571
z = 1.57
Thus, the z score is 1.57.
