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. Can you reject the hypothesis of no interactions?

Quizplus · Accepted Answer

To determine if there are interactions between curing time and temperature, we need to perform a two-way ANOVA with replication. If the interaction term is significant, then we can conclude that there are interactions between curing time and temperature. In this case, the p-value for the interaction term is less than 0.05, which means that we can reject the null hypothesis of no interactions and conclude that there are significant interactions between curing time and temperature. Therefore, the answer is A) True.
