Ummm let’s see.. yah I have no clue sorry buddy your just gonna have to get this one wrong
Answer:
An ANOVA test
Step-by-step explanation:
You will use the ANOVA test, which is a test that compares the means of more than 2 samples. Since the teacher used 3 test groups, she would have to use this test if she wanted to do a hypothesis test to determine if the means are equal.
*This test only tells us if the means are equal, it won't say which is greater than the other. You would have to do 3 individual hypothesis tests comparing 2 means at a time in order to determine that.
Range is all y-values. This would be all real numbers or (-oo,oo)
5*4^2-3*4*5=80-60=20
