Refer to the data below. Suppose X is the independent variable
and Y is the dependent variable. Calculate the variance of X,
variance of Y, standard deviation of X, standard deviation of Y,
the covariance between X and Y, the correlation coefficient between
X and Y, the slope of the regression line, the Y intercept of the
regression, ESS, RSS, TSS, and R-square of the regression line.
Predict the value of Y when X=25. Show your work by constructing
