Oly(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 an article. 180.5 181.7 180.8 181.5 182.6 181.7 181.2 182.2 182.2 180.2 181.7 180.5 compute the following. (round your answers to two decimal places.) (a) the sample range °c (b) the sample variance s2 from the definition [hint: first subtract 180 from each observation.] s2 = (c) the sample standard deviation s = (d) s2 using the shortcut method

Astudy was interested in determining if eating milk chocolate lowered someone's cholesterol levels. ten people's cholesterol was measured. then, each of these individuals were told to eat 100g of milk chocolate every day and to eat as they normally did. after two weeks, their cholesterol levels were measured again. is there evidence to support that their cholesterol levels went down? how should we write the alternative hypothesis? (mud = the population mean difference= before - after)a. ha: mud = 0b. ha: mud > 0c. ha: mud < 0d. ha: mud does not equal 0
