A pet association claims that the mean annual cost of food for dogs and cats are the same. The results for samples for the two types of pets are shown below. At a = 0.05, can you reject the pet association's claim? Assume the population variances are not equal. Assume the samples are random and independent, and the populations are normally distributed. Complete parts (a) through (e) below. Dogs Cats X, = $265 X2 = $230 S1 = $44 S2 = $40 n, = 17 n2 = 14 OA. t>6 OB. t< -6 C. t< -, t>to OD. -6
