I will be very honest, This is related to an assignment but i am not asking for the answers. I am just asking for guidance since it is kind of throwing me off.
Background The question that i am working on has 3 parts. The question refer to a scatterplot which has a regression line. The question says that "without using any" other information from the article, how would you say that X is impacting Y. I used the concept of slope in straight line and laid down the argument that since the slop is positive, it means that x is impacting y bla bla. I was able to answer the second question as well which was asking that if you have to go against it, how would you go. Again, just looking at the image.
Now the third question is asking that if you need any other statistical evidence, what it would be. I am not sure how to answer this. I mean the question is so vague that i don't even know what to google or read in different docs. I have read multple online tutorials but still confuse.
Can anyone give me a pointer? thanks
