Application Exercise: In a study of memoryr process, rats were rst presented with a fearinducing stimulus on a learning task as soon as they:r stepped across a line in a test chamber. Afterwards, the rats were divided and given electrical stimulation either 50 or 150 milliseconds after crossing the line. In addition, the rats had stimulation electrodes implanted in different areas in their brains (Neutral Area, Area A, or Area B). Researchers were interested in the time it to the animals to re-cross the line on a subsequent learning task. The idea is that stimulation of certain areas in the brain would interfere with memory and hence delay learning to avoid the line on the subsequent learning task. The data on time to re-cross the line are below. What can be concluded with an a: of 0.05?

Two-Way ANOVA V J b) Obtain/compute the appropriate values to make a decision about Ho.
