An experiment consists in throwing a die 5 times and noting the number of sixes. The experiment was repeated 200 times with the following results: No. of sixes: 0, 1, 2, 3, 4, 5 Frequency: 58, 86, 40, 14, 2, 0 Then the sample mean 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)?
