The trend of the plotted points has a positive slope, so we can eliminate -0.95 and 0. Next we need to determine how strong the correlation is from a scale of -1 to 1 where the strongest is closer to -1 or 1.

Since we cannot draw a line through all of the points, the answer cannot be 1.

Between 0.75 and 0.95, we should go with 0.95 because if we were to draw a best fit line through the points, most of them would be close to or on the line. If the answer was 0.75, the correlation would be much weaker.

So the answer is 0.95.
