true

1. based upon the data collected, which juice do you hypothesize contains the greatest amount of tannins?

○ cranberry
○ blueberry
● pomegranate
○ strawberry

1. in this study, the group that did not receive treatment is called the ______ group; this data is necessary to compare results of the various treatments reliably.

○ variable
○ guinea pig
○ control
○ treatment

Explanation:

Question 1

To determine if females consuming cranberry juice had the greatest UTI incidence compared to the no - juice group, we look at the bar graph. The "No juice" group has a much higher number of confirmed UTIs (around 13) than the "Cranberry" group (around 3). So the statement is false. But since the original selected option was "True", we correct it.

Tannins are known to help prevent UTIs. The group with the lowest number of UTIs is likely to have consumed juice with the most tannins. The "Pomegranate" group has the lowest number of UTIs (around 1 - 2), so we hypothesize pomegranate juice has the most tannins.

In an experimental study, the group that does not receive the treatment is called the control group. It is used as a baseline to compare the results of the treatment groups. The other options: "variable" is a factor being tested, "guinea pig" is a term for a test subject (not a group type in this context), and "treatment" group is the one that receives the intervention. So the correct term is "control".

Answer:

False
