A polymer chemist studied the effect of relative humidity (RH)
on the weight of molded parts made from a polymer material. The
chemist believes that any weight differences greater than 5 will
have a impact on the end use of the molded part. Use the data from
the study, provided below, to state conclusions about the effect of
relative humidity on the average and variability of the
