Consider the histogram for the above group of women according to the number of children they
had. Only part of the data set is given here.
True or false:
(a) The height of the rectangle for 4 or 5 children will be 7%.
(b) The area of the rectangle for 3 children will be 36%.
(c) The area of the rectangle for 4 or 5 children will be 14%.
(d) Since the percentage for 4 or 5 children is twice the percentage for 6 children, its rectangle
will be twice as high.
(e) To get endpoints for the rectangles of this histogram, in every case a correction of t1/2 is
needed.
