Question

If a normal distribution has a mean of 104 and a standard deviation of 6, what

Answer 1

Answer:  2

======================================

Explanation:

The greek letters mu and sigma represent the population mean and population standard deviation respectively.

mu = 104

sigma = 6

x = 116 is the raw score we want to convert to a z score

z = z score

z = (x-mu)/(sigma)

z = (116-104)/(6)

z = 12/6

z = 2

The positive z score tells us the raw score is above the mean.
