The decision of the test is to:
do not reject Họ
reject Ho
The final conclusion is:
There is enough evidence to reject the claim that at least one school has a different class size.
O There is enough evidence to support the claim that at least one school has a different class size.
O There is not enough evidence to support the claim that at least one school has a different class size.
