Solution
a). Variables tested in each condition:
Effect of submergence, temperature, wetness and apnea (independent variables) was studied on decrease of the heart beat (dependent variable)
b). The number of data points contributing to each class mean (n=#)
Saffron: Three data points viz., Submerged, 15oC and apnea contributed to mean -13.5bpm
Grey: Apnea contributed to mean -7.1bpm
Yellow: Wetness contributed to mean -5.6825bpm
Blue: Coldness contributed mean decrease of -11.175 bpm
