Continuous Probability Distributions
GOALS
When you have completed this chapter, you will be able to:
ONE
Understand the difference between discrete and continuous
distributions.
TWO
Compute the mean and the standard deviation for a unif
ESTIMATION
I. UNBIASED ESTIMATES
If the mean of the sampling distribution of a statistic
equals the corresponding population parameter, the statistic
is called an unbiased estimator of the parameter; otherwise,
it is called a biased estimator.

DISCRETE PROBABILITY DISTRIBUTIONS
DEFINITION OF A RANDOM VARIABLE
A random variable is a variable whose value is determined by
a random experiment.
