the number of visits to the doctor during the past year for each person. The data are as follows: Control Group Dog Owners 11 5 8 4 6 7 7 4 10 8 6 9 a. Is there a significant difference in the number of doctor visits between dog owners and control subjects? Use a two-tailed test with α = .05
Siegel (1990) found that elderly people who owned dogs were less likely to pay visits to their doctors after upsetting events than were those who did not own pets. Similarly, consider the following hypothetical data. A sample of elderly dog owners is compared to a similar group (in terms of age and health) who do not own dogs. The researcher records the number of visits to the doctor during the past year for each person. The data are as follows: Control Group Dog Owners 11 5 8 4 6 7 7 4 10 8 6 9
a. Is there a significant difference in the number of doctor visits between dog owners and control subjects? Use a two-tailed test with α = .05
In question 3, you are looking at the effect of having a dog compared to not having a dog on the number of doctor visits through the year. See class videos and this lesson's formula sheet. Is the research question a directional or non-directional question? Be sure and diagram your research first (see handout on diagramming your research) before you use the Two Independent Groups t test formula sheet to work the problem out.
