Dear friend
regarding answer choice B & E
How we can say that total number of treadmill in each group (motorized V.s NOn) is not important?
consider if only 20 motorized treadmills were sold, number of repaired is 2, and if 100 nonmotorized were sold, the number of repaired would be 2 as well. So, I think there would be an assumption regarding total number of each category as well for the conclusion to be true!
would you pls help me with this?
Thanks in advance for yourtime

According to a recent large-scale survey of people who had purchased new home exercise equipment during the past five years, ten percent of motorized treadmills purchased during that period had required repairs more than once, whereas only two percent of nonmotorized treadmills had ever needed repair. Therefore, people who want to buy a treadmill for regular workouts can rely on having their routine disrupted far less often if they buy a nonmotorized rather than a motorizedtreadmill.
