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 = 0.10, 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 X1 = $241 X2 = $206 = $40 = $36 = 18 n2 = 8 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 costs of food for dogs and cats are not equal." What are Ho and He? The null hypothesis, Ho, is My = H2. The alternative hypothesis, H., is My # 12 Which hypothesis is the claim? The alternative hypothesis, Ha The null hypothesis, Ho (b) Find the critical value(s) and identify the rejection region(s). Enter the critical value(s) below. (Type an integer or decimal rounded to three decimal places as needed. Use a comma to separate answers as needed.) VI More
