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 alpha = 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. (a) Identify the claim and state H_0 and H_a. Which is the correct claim below? A. "The mean annual cost of food for dogs is greater than the cost for cats."
B. "The mean annual costs of food for dogs and cats are not equal."
C. "The mean annual costs of food for dogs and cats are equal."
D. "The mean annual cost of food for cats is greater than the cost for dogs." What are H_0 and H_a?
The null hypothesis, H_0, is The alternative hypotheses, H_a, is Which hypothesis is the claim?
