Question

Fill in the blank to complete the statement.

The area under the normal curve to the right of μ equals​ _______.

A. σ

B. 1/2

C. 0

D. 1/σ√2π

Answer 1

The normal distribution curve is symmetrical about the mean (μ). As it has a total area = 1, 1/2 of the area falls to either side. Answer is (B) or 1/2.

You will also see that if you consult a normal distibution table. For z = 0 (0 std. deviations from the mean), the area under the curve to the left = 0.5000.
