Plot the length( on X axis) and MPG (on y) of the vehicles (on y) in a scatter diagram. The scatter diagram indicates that there is a correlation between the two. The correlation coefficient is -0.5

Plot the length( on X axis) and MPG (on y) of the vehicles (on y) in a scatter diagram. The scatter diagram indicates that there is no correlation between the two.

Create bins by using seven for the equal intervals. Compute the RELATIVE Frequencies and create the relative frequency histogram. The histogram appears to be skewed to the left.

Plot the cumulative relative frequency distribution. The sum of the relative frequencies (probabilities) reaches its maximum at 0.90, and the final cumulative relative frequency is also 0.90.
