Question
An engineer was studying the effect of curing temperature and curing time on the strength of a metal alloy.
a. The engineer claims that she has found a relationship between temperature and strength: by increasing temperature, she can increase the strength of the alloy. She also claims that she has found a relationship between time and strength: by decreasing time she can increase the strength of the alloy. Based on the above data, should you question the engineer's claim? Why or why not?
b. Suggest an experiment that would be better at helping the engineer explore the relationships between temperature, time, and strength?
