QUESTION 5

1. A hypothesis test is made for the following claim: the mean income for families of size four is greater than $40,000. For this test, what does a Type I error mean?
2. 1.We conclude the mean income for families of size four is greater than $40,000, when in fact it isn't.
3. 2.We conclude the mean income for families of size four is greater than $40,000
4. 3.We conclude the mean income for families of size four is not greater than $40,000, when in fact it is.
5. 4.A type I error is not possible.
