normal distribution problem - please help
Please help....
X supermarket is packing packets of frozen peas.
The weights of the packets of frozen peas are normally distributed with mean weight of 1.1 kg and standard deviation of 0.1 kg. The questions below in (a) and (b) all relate to this model.
X supermarket is concerned about the number of customers purchasing packets of frozen peas that are under the stated weight on the packet of 1 kg.
The company can reset the mean of their packaging machine for the frozen peas.
They wish to do this so that only 1% of the packets of frozen peas are under the stated weight of 1 kg. How does the mean setting on the machine have to be changed to achieve this. Note: Assume that the standard deviation setting remains at 0.1 kg.
