Answer 1

Based on your description of the data, it sounds like the points are plotted in a way that shows a strong positive trend, as they are in an "almost straight diagonal line" and are in the first quadrant with an increasing trend. Given the options provided, the best estimated correlation coefficient would likely be 0.80, as it suggests a strong positive correlation without being perfect (which would be indicated by a correlation coefficient of 1).

So, the best choice would be:

0.80
