Reference no: EM13137714

Machines are used to pack sugar in to packets supposedly containing 1.20 kg each.on testing a large number of packets over a long period of time,it was found that the mean weight of the packets was 1.24 kg and the standard deviation was 0.04 kg.A filled consecutively by the machine. Calculate the limits within which the weight of the packets should lie assuming that the machine is not been classified as faulty.
