3 A machine is designed to cut meter-sticks to be 1000 mm. long. 19 meter-sticks are measured, and it's found that they have a mean length of 1001.8 mm., with a standard deviation of 2.6 mm. To a 1% level of significance, can it be asserted that the standard deviation o of the process in general (i.e., of all the meter-sticks produced by the machine) is over 2 mm.? [Assume that the lengths of all the meter-sticks are normally distributed.]
