The person diameter of a certain hand pump is 0.7 inch. The manager determines that the diameters are normally distributed, with a mean of 0.7 inch and a standard deviation of 0.005 inch. After recalibrating the production machine, the manager randomly selects 26 pistons and determines the standard deviation is 0.0036 inch. Is there a significant evidence for the manager to conclude that the standard deviation has decreased
