In
this section, we will focus on continuous
probability distributions.
A continuous random variable has infinitely
many values, and those values are often
associated with measurements on a
continuous scale with no gaps or

After
selecting a sample, we know the
responses for the individuals in the sample,
but we usually take a sample to infer some
