question 18

Multiple Choice

Suppose a researcher collected data to compare whether dogs of different size categories differed in mean cost to a pet owner. Dogs were categorized as small, medium, or large. Cost was calculated as The average annual amount spent on food, veterinary visits, and medications. The calculated
F-statistic was 421.58. Given this test statistic, which of the following is the most reasonable
Conclusion?

• A) The F-statistic shows that variation between groups is larger than variation within groups, therefore, the researcher will likely conclude that there is an association between dog size and
• Mean cost to the pet owner.
• B) The F-statistic shows that large dogs have a significantly higher cost to the pet own than the other categories, therefore, the researcher will conclude that there is an association between
• Dog size and mean cost to the pet owner.
• C) The F-statistic shows that variation within groups is larger than variation between groups, therefore, the researcher will likely conclude that there is not an association between dog size
• And mean cost to the pet owner.
• D) None of these
