Question: Construct the cumulative frequency, cumulative relative frequency, and cumulative percentage distributions by using the frequency distribution table constructed for the data of Exercise.
Exercise: The following data give the repair costs (in dollars) for 30 cars randomly selected from a list of cars that were involved in collisions.
a. Construct a frequency distribution table. Take $1 as the lower limit of the first class and $1400 as the width of each class.
b. Compute the relative frequencies and percentages for all classes.
c. Draw a histogram and a polygon for the relative frequency distribution.
d. What are the class boundaries and the width of the fourth class?
