Is your life more fulfilling when you own a dog or cat? While some research suggests a pet in general can be positive for your life, other research suggests certain types of pets may improve life more than others....but the research is still inconclusive. To test the different influence a pet can have on people's lives, researchers measure one group of participant's life fulfillment with a dog and another group with a cat. Higher scores signify higher levels of life fulfillment. Using the data below, determine if there is a difference in life fulfillment for dog versus cat people. Test a = .05. Dog Exposure: 18, 19, 17, 18, 19 Cat Exposure: 17, 16, 18, 15, 16 a. Is there a significant difference in life fulfillment scores for the dog group compared to the cat group? Complete calculations by hand and submit handwork (document name must be Pet.Hand). Test at a = .05. b. Type your answer to the following questions using a = .05. i. Operational definition for IV = ii. Is the IV a discrete or continuous variable? iii. Operational definition for DV = iv. Step 1:H0: H1: v. Step 2:df = ___________a = ____________ critical value (t or z - highlight choice) = ___________ vi. Step 3: D = Dog, C = Cat MD = __________ SDD = ___________ MC = __________ SDC = ____________ Calculate r2 and then describe the result in terms of the specific IV and DV
