In a certain normal distribution of scores, the mean is 50 and the standard deviation is 6. Find the z-score corresponding to a score

of 60

a. - 1.67

b. 10.0

c. 1.67

d. 8.33

C is the correct answer: 1.67

Step-by-step explanation:

In this question, we are asked to calculate the z-score corresponding to a particular score given the standard deviation and the mean.

Mathematically, the z-score can be calculated as

z-score = (x - mean) / Sd

from the question mean is 50, standard deviation is 6 and x is 60

Plugging these values, we have

z-score = (60-50) / 6 = 10/6 = 1.67
