Please help me answer the following question:
Question 2 Suppose we have 505 observations in our data, and for each we have recorded two numeric attributes, x and 3:. Sample average of x is 0 Sample average of v is 500 Sample variance of): is 2500 Sample variance ofv is 10000 Note that our sample covariance is equal to the product of the correlation coefficient, sample standard deviation of x and sample standard deviation of v, i_e_, s1W = [xv sx s,\"r Suppose our sample covariance, s is 4500, then our correlation coefcient is closest to: [:1 0.3 [:1 0.3 [:1 0.5 C] 0 [:1 0.5 w: Again, suppose our sample covariance, s I?
