Based on the description of the eleven points plotted in a diagonal pattern in the first quadrant, it suggests a strong positive linear relationship between the x and y values. Since the points are increasing in trend, the best estimated correlation coefficient among the given choices would be 0.9.
Thus, the best choice is 0.9.
