Consider the data on the right a Draw a scatter diagram of t

Consider the data on the right. (a) Draw a scatter diagram of the data and compute the linear correlation coefficient. (b) Draw a scatter diagram of the data and compute the linear correlation coefficient with the additional data point left parenthesis 10.5 comma 9.4 right parenthesis(10.5,9.4). Comment on the effect the additional data point has on the linear correlation coefficient. Explain why correlations should always be reported with scatter diagrams.

Solution

Data for the scatter diagram is missing in the question.

Anyways use this formula to get the linear correlation coefficient.
