Chapter 7
This type of variable has a
countable number of
outcomes
Categories
Categories
Discrete
The normal distribution is this type of
probability distribution
Categories
Categories
continuous
This is what the law of large numbers
means
Categories
Categories
As the number of observations
increases, the mean of the observed
values eventually approaches the mean
of the population
This is how to find
the mean of a discrete distribution

These are the three pieces of information
you must have in order to find a binomial

This distribution allows you to find the
probability of having a certain number
of failures before your first success

Suppose you purchase a bundle of 10 bare-root broccoli
plants. The sales clerk tells you that on average you can
expect 5% of the plants to die. Find the probability that
you will lose at most one of the broccoli plants.

is actually true
Meaning of a type II error

We accept the null hypothesis but it is
actually false
Chapter 3/4 400 Points
This is the probability that a test will
reject the null when it is not true
