Weight Away, a company that sells weight-loss plans, often advertises the effectiveness of its plans by highlighting the stories of a few clients who have lost extraordinary amounts of weight. To get a better indication of the general effectiveness of the plans, we asked Weight Away to send us information about "typical" clients. Weight Away mailed us a brochure with the following histogram, which displays the weight loss (in pounds) over the past month for 50 Weight Away clients. (Note that a negative value for weight loss represents a weight gain.) Frequency 15 12 10 10 S 0- -10 . 10 . 20 30 40 50 Weight loss (in pounds) Based on the histogram, draw the ogive (the cumulative relative frequency polygon) for the Weight Away data.
