From Veronica’s study 

From Bella’s study 

How will their Mean Group Diff statistics and p-values compare? 

A. Veronica will get a larger Mean Group Diff statistic and smaller p-value. 

B. Bella will get a larger Mean Group Diff statistic and smaller p-value. 

C. Veronica and Bella will get the same Mean Group Diff statistic, but Veronica will get a smaller p-value. 

D. Veronica and will Bella get the same Mean Group Diff statistic, but Bella will get a smaller p-value.
