Question

Before you proceed and explore on computing probabilities under the normal

curve, let us see how much you know before we tackle the lesson. Below is a 5-item

true or false test. Determine whether the statement is true or false. Write T if the

statement is true and F if false on the blank provided before each number.

1. Probability value is a number from 0 to 1.

2. Probability value is a number from −1 to 1.

3. Finding the area of a region is the same as finding the probability

associated with that region.
