Extracted text: In a histogram, the proportion of the total area which must be to the right of the mean is: O A. exactly 0.50 if the distribution is symmetric and unimodal B. less than 0.50 if the distribution is skewed to the left C. exactly 0.50 D. exactly 1.0 if the distribution is symmetric and bimodal E. more than 0.50 if the distribution is skewed to the right Generally speaking, if two variables are unrelated (as one increases, the other shows no pattern), the covariance will be: O A. a positive or negative number close to zero O B. a large negative number C. a large positive number D. none of the above
