Problems 1-4 are from section 4.1 #2: Think about a density curve that consists of two straight-line segments.

The first goes from the point (0, 1) to the point (0.7, 1) then the second goes from the point (0.7, 1) to the

point (1.3, 0)

2. What is the probability that X lies between 0.7 and 1.3?

a. 0.5

b. 0.8

c. 0.3

e. none of these

3. What is the probability that X is equal to 0.5?

a. 0.5

b. 0.8

c. 0.3

d. 0

e. none of these

4. What is the probability that X lies above 0.2

a. 0.5

b. 0.8

c. 0.3

d. 0

e. none of these

5. Suppose a density curve is defined by the function f(x) = 2.5 for all values between x = 0 to x = 0.4.
