Answer 1

Based on the description of the plot, it seems that there is a positive correlation between the time spent studying and the scores on a test, as the points are arranged in a scattered increasing curved pattern in the first quadrant.

The best estimated correlation coefficient among the given choices would be 0.98. This indicates a very strong positive correlation, which aligns with the observation of an increasing trend in the data.

Therefore, the best answer is 0.98.
