The mean of three numbers is 32. The range of this data set is 28, while the difference between the two smallest numbers is 8. The greatest of the three numbers is:

In a moderately skewed distribution, if Mean = 12 and Median = 8, then using Empirical relation (Mode = 3 Median - 2 Mean), what is the value of Mode?

If 4y - 5x = 15 is the regression line of y on x and the coefficient of correlation between x and y is 0.75, what is the value of the regression coefficient of x on y (bxy)?
