A pet association claims that the mean annual costs 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 equal. Assume that the samples are random and independent, and the populations are normally distributed. Complete parts (a) through (e). Dogs X $253 S = $29 n = 18 Cats x2 = $229 $2 = $27 n2=15 (a) Identify the claim and state Ho and Ha What is the claim? A. "The mean annual costs of food for dogs and cats are equal." B. "The mean annual cost of food for cats is greater than the cost for dogs." OC. "The mean annual costs of food for dogs and cats are not equal." D. "The mean annual cost of food for dogs is greater than the cost for cats." The null hypothesis, Ho, is The alternative hypothesis, Ha, is H2. The hypothesis is the claim. A pet association claims that the mean annual costs of food for dogs and cats are the same.
