Question

Consider a normal distribution with a mean of 14 and variance of 26. What is the Z score for the value of 16?

Answer 1

Answer #1

Solution :

Given that ,

mean = $\mu$ = 14

variance = $\sigma$ ² = 26

standard deviation = $\sigma$ = $\sqrt{}$ $\sigma$ ² = $\sqrt{}$ 26 = 5.10

x = 16

Using z-score formula,

z = x - $\mu$ / $\sigma$

z = 16 - 14 / 5.10

z = 0.39
