Question:

1. The normal probability is applied to
a. A continuous random variable
b. A discrete random variable
c. Any random variable
2. For a continuous random variable, the probability of a single value of x is always
a. Zero
b. 1.0
c. Between 0 and 1
3. Which of the following is not a characteristic of the normal The total area under the curve is 1.0.
b. The curve is symmetric about the mean.
c. The two tails of the curve extend indefinitely.
d. The value of the mean is always greater than the value of the standard deviation.
4. The parameters of a normal are
a. µ, z, and σ
b. µ and σ
c. µ, x, and σ
5. For the standard normal µ = 0 and σ = 1
b. µ = 1 and σ = 0
c. µ = 100 and σ = 10
6. The z value for for a normal curve is always
a. Positive
b. Negative
c. 0
7. For a normal curve, the z value for an x value that is less than is always
