To study the effect of curing temperature on shear strength of a certain rubber compound, 65 specimens were cured at 150°C and 105 were cured at 130°C. The specimens cured at 150°C had an average shear strength of 620 psi, with a standard deviation of 20 psi. Those cured at 130°C had an average shear strength of 750 psi, with a standard deviation of 30 psi
