2) Two random variables have zero mean and variances of 16 and 36. Their correlation coefficient is 0.5. Find the variance of their sum, Z = X + Y. Find the variance of their difference, W = X - Y. Find the correlation of coefficient ρZ, W Define Covariance matrix K for X, Y, Z, W. Repeat a-d if X and Y are uncorrelated.

1. If the linear correlation coefficient of two variables is zero, then there is no _______________ relationship between the variables. A linear correlation coefficient of 0.92 suggests a ________________ linear relationship than a linear correlation coefficient of -0.86. The value of the ___________________ always lies between -1 and 1, inclusive. If the linear correlation coefficient of the regression line is negative, then the ____________________ of the least squares (linear) regression line must be negative. Give a detailed interpretation of the...

Why is it advisable to generate a scatterplot before computing a correlation coefficient between two variables?...

Why is it advisable to generate a scatterplot before computing a correlation coefficient between two variables? Describe how a scatterplot might differ when viewing correlations that represent positive, negative, and no relationship between predictor and criterion variables. Is it possible to have a relation between variables that systematic (i.e., reliable and predictable) yet not linear?
