Two skaters are ready to skate on a cicular skating platform. Skater A is at a distance of 3 m from the center and skater B is at a distance of 6 m from the center. After 10 revolutions of their skating, how much distance would have B traveled more than A? Give answer in terms of π . =..

A company claims that the standard deviation of the gear speed for a piece of machinery is 28 revolutions per minute (rpm). An engineer selected a random sample of 20 machines and found the standard deviation as 40 (rpm). At α = 0.01, is there enough evidence to reject the company's..
