It is essential in manufacture of machinery to utilize parts which conform to specifications. In the past, the diameters of ball bearings produced by certain manufacturer had variance of .00156. To cut costs, the manufacturer instituted less expensive production techniques. The variance of the diameters of 100 randomly sampled bearings produced by new procedure was .00211. Do the data provide sufficient evidence to point to that the diameters of ball-bearings produced by new procedure are more variable than those produced by old process? test at α=.01
