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 = 0.01, 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, = $261 X - $226 S, = $39 52 = $35 n, = 15 n2 = 9 (a) Identify the claim and state Ho and H Which is the correct claim below? O A. "The mean annual costs of food for dogs and cats are not equal." B. "The mean annual costs of food for dogs and cats are equal." O C. "The mean annual cost of food for cats is greater than the cost for dogs." O D. "The mean annual cost food for dogs is greater than the cost for cats." What are Ho and H,? The null hypothesis, Ho, is 2. The alternative hypothesis, H, is 2- Which hypothesis is the claim? The null hypothesis, Ho The alternative hypothesis, H
