There is plenty of research into the best way to motivate people, but this research is interested in what motivates pets. Researchers use dogs and use praise or treats to reward behavior at the end of the month (they test to see which group of dogs can sit the quickest). One group of dogs is rewarded with praise (e.g., "good dog") when they sit and the other group of dogs is rewarded with a dog treat when they sit. At the end of the training (1 month later) researchers test each dog by saying "sit" and timing how quickly each dog sits (measured in seconds). Researchers believe that the dogs who were rewarded with treats will sit more quickly. The numbers of seconds it takes each dog to sit can be see below. Test with = .05.

Complete the most appropriate test statistic and type the calculated values here (central tendency value(s), variability measure, calculated test value). f. Interpret the significance of the results of the test statistic using specific IV and DV descriptors with calculated test statistic value and critical value(s) as support. g. Calculate and interpret percentage of variance for this scenario
