Answer:
The best estimate of the correlation coefficient is 0.9 from the given data.
Step-by-step explanation:
From the scatter plot, the line of best fit will have a positive slope.
So, the correlation coefficient , 
is greater than 0.
so, ≠ - 0.9
Also, there is a deviation from absolute linearity.
So, ≠ 1
Again from the scatter plot it is closer to linearity than further.
Hence, ≠ 0.3 .
So = 0.9
