Some researchers claim there is an association between owning a dog and developing a flea infestation at home. They took a random sample of people living in St. Louis, Missouri, and recorded whether they had a dog and whether they had a flea infestation in their home. The results are shown in the following two-way relative frequency table:


Has Flea Infestation Does Not Have Flea Infestation Row Totals
Does not have a dog 0.015 0.652 0.667
Has one dog 0.022 0.261 0.283
Has more than one dog 0.032 0.019 0.050
Column Totals 0.069 0.931 1
