(a) A golf instructor examined student data. He found that when a student takes longer to hit, it implies that the ball will lan
d closer to the hole. What can he conclude?
A) There is no correlation between amount of time before hitting and distance from the hole.
B) There is a correlation between amount of time before hitting and distance from the hole. There may or may not be causation. Further studies would
have to be done to determine this.
C) There is a correlation between amount of time before hitting and distance from the hole. There is probably also causation. This is because there is a
decrease in the distance from the hole with an increase in the amount of time before hitting.
According to the examination, the longer a student takes to hit, then the closer the ball is to the hole, therefore there is correlation. Now, this doesnt imply that in order to make it closer to the ball you just need to wait longer because that doesnt seem true. Probably the most skilled students take some time to hit in order to make the hit accurate, thus the longer the hit the closer the ball is to the hole (because they were hit by skilled students). This is just an hypothesis though, but it is still true that it will be needed more studies to determine if there is causation or not; so i stay with optionB.
The Triangle Inequality Theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side.
If you add 2 and 4, you will get 6. This is the right answer because the only answer that is incorrect is the 4th, it has to equal a minimum of 7, not 6.
