Explore the interaction in the pacemaker delamination data introduced in Problem 8.4.

Problem 8.4

Implantable heart pacemakers contain small circuit boards called substrates. These substrates are assembled, cut to shape, and fired. Some of the substrates will separate, or delaminate, making them useless. The purpose of this experiment was to study the effects of three factors on the rate of delamination. The factors were A: firing profile time, 8 versus 13 hours with the theory suggesting 13 hours is better; B: furnace airflow, low versus high, with theory suggesting high is better; and C: laser, old versus new, with theory suggesting new cutting lasers are better A large number of raw, assembled substrates are divided into sixteen groups. These sixteen groups are assigned at random to the eight factor level combinations of the three factors, two groups per combination. The substrates are then processed, and the response is the fraction of substrates that delaminate. Data from Todd Kerkow

Analyze these data to determine how the treatments affect delamination.
