This is how the problem starts out: A meter stick is placed with the fulcrum at the 50-cm mark. If a 120-g mass is placed at the 25-cm mark and a 25-g mass at the 10-cm mark, where should a 500-g mass be placed to balance the system? I thought that since

What happens to the power of the z test, when the standard deviation increases? The deviation from the mean must be larger to obtain the same significance level. I'm not familiar with the term "power" (we don't use that term in physics), but I would guess
