Question

A vertical line is drawn through a normal distribution at z = 0.50, and separates the
distribution into two sections. What proportion of the distribution is in the larger section?
a. 0.6915
b. 0.3085
c. 0.1915
d. 0.3830

Answer 1

You don't even need a set of Normal tables to answer this one. Just remember that the total area under the curve is 1; note that you've been asked to find the proportion of the distribution in the larger section, and then look at the four options. How many answers greater than 0.5 are listed?

Answer 2

0.3085
