Question

If a normal distribution has a mean of 44 and a standard deviation of 8, what is the z-score for a value of 46?

Answer 1

use the formula

z = (x-mu)/sigma

Answer 2

mu = 44 (population mean)
sigma = 8 (population standard deviation

Answer 3

raw score: x = 46

z-score: z = unknown (for now)

Answer 4

yea i just wanted to check my answer, i got 1/4

Answer 5

yes or 0.25

Answer 6

it's probably better to convert to decimal notation so you can use a table when it comes to looking up areas under the curve
