On which axis is mpg plotted? b) Construct a histogram of the number of forward gears. c) Write code to return a numeric summary of the mtcars dataset. d) Construct a boxplot of the miles per gallon. Use suitable colors. Create a heading. If your boxplot displays scientific notation turn it off. (as shown in lecture). e) On one chart, produce side-by-side boxplots to compare miles per gallon to the number of gears. Use suitable colors, add a heading and include horizontal and vertical labels
