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 mega Pascal’s.

(a) Show a dot plot of the data with both low and high temperature tensile strength values.

(b) Compute sample mean tensile strength for both samples

(c) Does it appear as if curing temperature has an influence on tensile strength based on the plot? Comment further.

(d) Does anything else appear to be influenced by an increase ion cure temperature? Explain.
