Which of the following are measures of the linear relationsh

Which of the following are measures of the linear relationship between two variables? A. The variance B. The coefficient of correlation C. The covariance D. Both the covariance and the coefficient of correlation In a histogram, the proportion of the total area which must be to the right of the mean is: A. exactly 0.50 B. exactly 0.50 if the distribution is symmetric and unimodal C. more than 0.50 if the distribution is skewed to the right D. less than 0.50 if the distribution is skewed to the left E. exactly 1.0 if the distribution is symmetric and bimodal

Solution

B. The coefficient of correlation measures strength of linear relationship
