7) Many researchers have noted a decline in "personal meaningfulness" as people age. However, the results from other research suggest that the interacting with animals, such as dogs, may reduce and even reverse these age-related declines. To examine this phenomenon, suppose a researcher obtains a sample of n = 16 adults who are between the ages of 65 and 75. The researcher uses a standardized test to measure "personal meaningfulness" for each individual. The participants then begin a 2-month program in which they interact weekly with a variety dogs. At the end of the 2-month period, the researcher again measures the "personal meaningfulness" for each participant. The scores are provided below. By how much does the "personal meaningfulness" of the population of elderly Before Dog Interaction After Dog Interaction adults increase after interacting with the dogs?
