Question

The proportion of scores less than z = 0.00 is

a. 0.00
b. 0.50
c. 1.00
d. -0.50
e. impossible to compute from the information given

Answer 1

The proportion of scores less than z = 0.00 is 0.00.

Step-by-step explanation:

The proportion of scores less than z = 0.00 is a. 0.00. When the z-score is 0.00, it corresponds to the mean of the distribution. Since the mean is in the middle of the distribution, the proportion of scores less than the mean is 0.00. This means that no scores are less than z = 0.00.
