The heights of 20-year-old females  are normally distributed with a mea n of 64 inches  and a standard deviation of 2 inche s. What is the z-score for a height  of 67 inches?

1.5

Step-by-step explanation:

Applying,

Z = (x-μ)/σ Equation 1

Where Z = Z score for a height of 67 inches, x = height, μ = mean of the height, σ = standard deviation of the height.

From the question,

Given: x = 67 inches, μ = 64 inches, σ = 2 inches.

Substitute these values into equation 1

Z = (67-64)/2

Z = 3/2

Z = 1.5

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point
