E. side-by-side boxplot.To graphically represent the relationship between the variables TRAVEL TIME and SALARY it is most appropriate to use a A. Pareto chart. B. bar chart. C. side-by-side boxplot (or parallel boxplot). D. scatterplot. E. pie chartIt is assumed that the lifetime ofa particular type of battery is normally distributed with mean of 200 hours and a standard deviation of 25 hours.
