Module Hypothesis Testing
Type I and Type II Checkpoint
Step 1 of 1
Question 1 of 6 Points: 10 out of 10
Food inspectors inspect samples of food products to see if they are safe. This can be thought of
as a hypothesis test with the following hypotheses.
• H0: the food is safe
• Ha: the food is not safe
The following is an example of what type of error?
The sample suggests that the food is safe, but it actually is not safe.
type I
type II
not an error
Good job! The statement describes a situation where we fail to reject a false null hypothesis. This
is a type II error.
Question 2 of 6 Points: 10 out of 10
Food inspectors inspect samples of food products to see if they are safe. This can be thought of
as a hypothesis test with the following hypotheses.
• H0: the food is safe
• Ha: the food is not safe
The following is an example of what type of error?
The sample suggests that the food is not safe, but it actually is safe.
type I
type II
not an error
Good job! The inspector’s conclusion here is that H0 is false (the food is not safe). But H0 is
actually true (the food is safe).
