Based on the description provided, the points are plotted in a diagonal pattern in the first quadrant, indicating a strong positive correlation as the points are moving upwards from left to right.
Given that the trend is described as increasing and the points follow a diagonal line pattern, the best estimated correlation coefficient from the choices provided is:
**0.9**
This indicates a strong positive correlation. A correlation coefficient of 1 would indicate a perfect linear relationship, which may not be the case if there are slight deviations among the points. Therefore, 0.9 is the most appropriate estimate.
