The tensile strength of silicone rubber is thought to be a function of curing temperature. A study was carried out in
which 12 specimens of the rubber were prepared using curing temperatures of 20°C and 45°C. The accompanying
data table shows the tensile strength values in megapascals. Compute the sample standard deviation in tensile
strength for the samples separately for the two temperatures. Does it appear as if an increase in temperature
influences the variability in tensile strength? Explain.
