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.
Answer:
I’m so tired, i thought you asked what the absolute devisation of Aries is?
Step-by-step explanation:
Option b is the better deal
There is no information given about point V, so any answer will do for the question asked.
If we assume the intent is to ask about the image of point Z, then its coordinates will be 0.8 times those of point Z.
Z' = 0.8×(5, -4)
Z' = (0.8×5, 0.8×(-4)) = (4, -3.2)
The appropriate choice seems to be
C (4, -3.2)
