Answer:
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
