# Answer to Question #32057 in Statistics and Probability for Jake

Question #32057

The next 2 questions refer to the following scenario. Suppose the manager of a pet store wants to determine if there is a difference in the amount of money spent in the store, on average, by owners of dogs vs. owners of cats. Consider dog owners as group 1 and cat owners as group 2. Assume that the population standard deviations are equivalent between groups. Below are the sample data for the nine dog owners and the 9 cat owners. Test the hypothesis at alpha equals 1%.

The hypothesis at Ho: µ1 = µ2 vs. Ha: µ1 ≠ µ2.

Group1 Group 2

36 35.5

19 32.5

24.5 30

27 31.5

20 35.5

35 38

24.5 34.5

23.5 36

27.5 26

15) What is the p-value and test statistic used to test this hypothesis?

a) 0.0162 2.134

b) 0.9961 -2.134

c) 0.0339 3.044

d) 0.0756 3.044

e) 0.0077 -3.044

16) Is there a significant difference in the amount of money spent in the pet store, on average, by owners of dogs vs. c
