Which is the best estimate of the correlation coefficient for the scatter plot?

olga55 [171]

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 , $\rho$ is greater than 0.

so, $\rho$ ≠ - 0.9

Also, there is a deviation from absolute linearity.

So, $\rho$ ≠ 1

Again from the scatter plot it is closer to linearity than further.

Hence, $\rho$ ≠ 0.3 .

So $\rho$ = 0.9

Can someone pls help? Thx

sergey [27]

Your answer would be -3/4n+3/8 because 1/4•-3/1n would be -3/4n and then 1/4•3/2 would be 3/8 so your answer would then be -3/4n+3/8.
