A student team in a business statistics course performed a factorial experiment to investigate the time required for pain relief tablets to dissolve in a glass of water. The two factors of interest were brand name Equate, Kroger or Alka -Seltzer, and temperature of the water hot or cold. The experiment consisted of four replicates for each of the six factor combinations. The following data stored in pain relief show the time a tablet took to dissolve (in seconds) for the 24 tablets used in the experiment.
