Introduction.
We have seen how to describe sample data using graphical methods and summary statistics
(see Section 1). We

Some particular random variables.

The binomial random variable.
This is based on a simple random event called a Bernoulli trial. This event has only two
outcomes:
success with Pr(success) = p

Probability
2.1
The concept of probability arises in different ways.
2.1.1 Using sample data we can associate the idea of probability with relative frequency.
The following table gives the frequency

In their simplest form Control Charts are an application of the Central Limit Theorem
to manufacturing proCesses. The early ideas were developed by Walter Shewhart at

It was noted earlier that sample spaces can be either discrete (finite or infinite but
countable) or continuous (uncountable). For each type of sample space we can define a
