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
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?
