Question
A potato chip manufacturer was building a new manufacturer plant and tgey were trying to decide whether or not they wanted to change the equipment/machine they were currently to bag the chips. They randomly sampled the weights of 50 bags from their current machine and 50 bags from their new machine and both of them recorded a average weight of 10 onces. However the current machine had a deviation of 0.14 once and the new machine had a standard deviation of 0.11 once. Carry outvthe appropriate hypothesis at a= 0.05 level of significance to determine if the variability of the potato chip bag weights is lower with the new machine as opposed to the one the company is currently using.
