Answer 1

Answer:

see image

Step-by-step explanation:

put the points from the table on the graph. Like time is the x and drinks is the y. These are the variables: time and number of drinks. Go over to 11, then up to 20, put a point there, etc. Do this for all five pairs of the numbers in the table. Imagine a line that goes thru the data points. See image. It is a pretty good line for the data. The points come pretty close to the line, where they miss is sort of random and on both sides of the line. This is a good thing. The line goes up, so the correlation is positive. When the line is a good line the correlation coefficient, r is 1 or -1. A bad line that doesn't match the data is smaller decimals like the .5 or -.5

Here its good and positive, so r=1
