# Question

A box of Wheat Chex cereal is to be filled to a mean weight of 466 grams. The lower specification limit is 453 grams (the labeled weight is 453 grams) and the upper specification limit is 477 grams (so as not to over fill the box). The process standard deviation is 2 grams.

(b) Assess the process capability.

(c) Why might it be dif - cult to reduce the variance in this process to raise the capability indices?
