An exercise physiologist compared the perceived exertion of women between the ages of 20 and 25 who exercised with three different pieces of equipment - a stationary bicycle, a treadmill, and free weights. Perceived exertion was rated on a scale of 1 to 50. Eighteen women, randomly divided into three groups, used the exercise equipment for 30 minutes before rating their perceived exertion. Assuming ordinal data, test if there were differences among the three kinds of exercise. Use a = .05
