Let x1 y1 x2 y2 and x3 y3 be a simple random sample from a population of bivariate data The variable X is x1 x2 and x3 The variable Y is y y2 and Y3 The values of the terms in the sample are in the table below A fourth point 2 y4 will be added to the dataset Let r be the correlation coefficient between X and Y i 1 2 3 Xi Vi 1 1 0 0 1 1 A After the fourth point is added what is the sample size n B After the fourth point is added if r is equal to 1 0 calculate y4 C After the fourth point is added if r is equal to 0 0 calculate y4 D After the fourth point is added is it possible that r is equal to 1 0 Explain why or why not
