A data set on money spent on lottery tickets during the past year by 200 households has a lowest value of $1 and a highest value of $1167. Suppose we want to group these data into six classes of equal widths.
a. Assuming that we take the lower limit of the first class as $1 and the width of each class equal to $200, write the class limits for all six classes.
b. What are the class boundaries and class midpoints?
