#1 Consider the following data set, in which shrinkage is measured once again at low injection velocity and high injection velocity. However, this time the mold temperature is raised to a high level and held constant. Shrinkage values at low injection velocity: 76.20 76.09 75.98 76.15 76.17 75.94 76.12 76.18 76.25 75.82 Shrinkage values at high injection velocity: 93.25 93.19 92.87 93.29 93.37 92.98 93.47 93.75 93.89 91.62 (a)Check the distributions of the data. (b)Whether distribution is (i) leptokurtic (ii) meso-kurtic (iii) platy-kurtic
