Let us hypothesize that cats spend more time sleeping in Winter than in Summer. Let us also presume that in Summer, cats sleep an average of 15 hours per day and we will be observing the sleep patterns of cats during Winter for comparison. Using the notation below, identify the four possible hypotheses. Then describe each of those hypotheses within the context of this cat-sleep study. H0: µ=µhyp Halt:  µ ≠µhyp Halt2: µ>µhyp Halt3: µ<µhyp
