Student:
1. A continuous random variable is characterized by uncountable values and can take on any value within an
interval.
True False
2. We are often interested in finding the probability that a continuous random variable assumes a particular
value.
True False
3. The probability density function of a continuous random variable can be regarded as a counterpart of the
probability mass function of a discrete random variable.
True False
4. Cumulative distribution functions can only be used to compute probabilities for continuous random
variables.
True False
5. The continuous uniform distribution describes a random variable, defined on the interval [a, b], that has
an equally likely chance of assuming values within any subinterval of [a, b] with the same length.
True False
6. The probability density function of a continuous uniform distribution is positive for all values between -
∞
and +
∞
.
True False
7. The mean of a continuous uniform distribution is simply the average of the upper and lower limits of the
interval on which the distribution is defined.
True False
8. The mean and standard deviation of the continuous uniform distribution are equal.
True False
9. The probability density function of a normal distribution is in general characterized by being symmetric
and bell-shaped.
True False
10. Examples of random variables that closely follow a normal distribution include the age and the class year
designation of a college student.
True False
11. Given that the probability distribution is normal, it is completely described by its mean μ > 0 and its
standard deviation σ > 0.
True False
12. Just as in the case of the continuous uniform distribution, the probability density function of the normal
distribution may be easily used to compute probabilities.
True False
13. The standard normal distribution is a normal distribution with a mean equal to zero and a standard
deviation equal to one.
True False
