Statistics questions!
1) 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?
Can someone show a step by step process on how to go about answering these problems?? I am getting stuck. Please and thank you.

Best ResponseYou've already chosen the best response.1first step to me is to write down the classes, starting at 1 and partitioning them (moving by) 200 1 200 400 600 etc ... these form the left side boundaries of each class, fill in the right sides ... usually 1 less then the value of the NEXT class 1  199 200  399 400  599 600  799 etc ... now that the classes are bounded left and right, what is the middle value of each class? the average of the endpoints ...
