Question is Attached in image.
A control system wasinstalled to regulate the weight of potato chips dumped into bagsin a packaging
operation. Given samples of 15 bags drawn from the operation before and after the control system
was installed, evaluate the success of the system. Do this by comparing the arithmetic mean and
standard deviations before and after. The bags should be 200 g.
Samples before: 201, 205, 197, 185, 202, 207, 215, 220, 179, 201, 197, 221, 202, 200, 195
Samples after: 197, 202, 193, 210, 207, 195, 199, 202, 193, 195, 201, 201, 200, 189, 197
