• • 6.7 Consider the types of poor driving habits that might occur at a traffic light. Make a list of the 10 you consider most likely to happen. Add the category of “other” to that list.

a) Compose a check sheet [like that in Figure 6.6(a)] to collect the frequency of occurrence of these habits. Using your check sheet, visit a busy traffic light intersection at four different times of the day, with two of these times being during hightraffic periods (rush hour, lunch hour). For 15 to 20 minutes each visit, observe the frequency with which the habits you listed occurred.

b) Construct a Pareto chart showing the relative frequency of occurrence of each habit.
