The tensile strength of silicone rubber is thought to be a function of curing temperature. a study was carried out in which samples of 12 specimens of the rubber were prepared using curing temperatures of 20◦c and 45◦c. the data below show the tensile strength values in megapascals.(20 c) 2.07 2.14 2.22 2.03 2.21 2.03 2.05 2.18 2.09 2.14 2.11 2.05(45 c) 2.52 2.15 2.49 2.03 2.37 2.05 1.99 2.42 2.08 2.42 2.29 2.01(a) show the dot plot of the data with both low and high temperature tensile strength value(b) compute sample mean tensile strength for both samples
