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.
4 feet is 48 inches.
So 4'2" would be 50 inches.
50/5=10
The class needs to make 10 tiles.
11.25 - 10.5 = 0.75
Knowing that this is the profit she makes with one share, so:
20 * 0.75 = 15
Caroline made $15 profit.
