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
-0.5 n^2=-18
n^2= 36
n= sqrt (36)=6 or -6
