Suppose that you have a sample of data consisting of n-135 observations. Further, suppose that you have two variables in the dataset, X and Y. In addition, the sample standard deviation of X is 125.36, sample covariance between X and Y is 23,278.10 and the sample correlation coefficient between X and Y is .95. Knowing this, what is the sample standard deviation of Y be?
