#12 Driving: Bad Habits Driving would be more pleasant if we didn’t have to put up with the bad habit of other drivers. USA Today reported the results of a Valvoline Oil Company survey of 500 drivers, in which the drivers marked their complaints about other drivers. The top complaints turn out to be tailgating, marked by 22% of the respondents; not using turn signals, marked by 19%; being cut off, marked by 16%; other drivers driving too slowly, marked by 11%; and other drivers being inconsiderate, marked by 8%. Make a Pareto chart showing percentage of drivers listing each stated complaint. Could this information as reported be put in a circle graph or pie chart? Why or why not?
