Question

2. Suppose we wanted to compare the heights of two students: Joe, a 69-inch-tall student in this class (where y = 65.5 inches and = 3.06 inches), and Michael, a 65-inch-tall student in a different class (where y=64.0 inches and 2.75 inches). Show your work to determine which student is taller, compared to his peers, and explain how you came to your conclusion.

Answer 1

We are given,

Joe height = x = 69

and

u=65.5

0 = 3,06

Z can be computed as

Z=x-u 2_69–65.5 3.06 Z = = z = 1.14

And

Michael height y = 65

with

u= 54

= 2.75

z can be computed as,

z=ソール | 65-64 z= 12.75 z=0.36

Here z-value of Joe is greater than z-value of Michael. Hence, Joe is taller than Michael.
