Poly(3-hydroxybutyrate) (phb), a semicrystalline polymer that is fully biodegradable and biocompatible, is obtained from renewable resources. from a sustainability perspective, phb offers many attractive properties though it is more expensive to produce than standard plastics. the accompanying data on melting point (°c) for each of 12 specimens of the polymer using a differential scanning calorimeter appeared in the article “the melting behaviour of poly(3-hydroxybutyrate) by dsc. reproducibility study” (polymer testing, 2013: 215–220).180.5 181.7 180.9 181.6 182.6 181.6 181.3 182.1 182.1 180.3 181.7 180.5compute the following: a. the sample meanb. the sample medianc. let yi = original measurement i – 100. the sample mean and standard deviation of y. d. what do you notice about the differences in the sample mean and standard deviation of the original values and those values for y?
