Population and Sampling Distribution

Question 1 A: For a normal distribution that has a mean of 100 and a standard deviation of 8. Determine the Z-score for each of the following X values:

X = 108

X = 112

X = 98

X = 70

X = 124

(A)

Z = (X value - Mean) / Standard Deviation

Z = (X - µ) / d

For the given question,

X = 108

Mean = µ = 100

Standard Deviation = d = 8

By putting these values in the formula, we get:

Z = (108 - 100) / 8

Z = 8 / 8

Z = 1.00

(B)

For the given question,

X ...
