An Experiment Is Conducted to Study the Effects of Curing $\alpha = 0.05$

question 1

Short Answer

An experiment is conducted to study the effects of curing times and curing temperatures on the bonding strength of an epoxy adhesive. In the experiment, two steel rods are adhered together end-to-end, and the bonding strength is defined as the force, in pounds, required to pull the bond apart. For each combination of curing time and curing temperature, three tests are performed. The results of the experiment are shown below. i). Can you reject the hypothesis of no interactions?
ii). Can the main effect of curing temperature (low or high) on bonding strength be interpreted? If so, interpret
the main effect using the α = 0.05 level of significance.
iii). Can the main effect of curing time on bonding strength be interpreted? If so, interpret the main effect using
the $\alpha = 0.05$ level of significance.
