You conduct a study to investigate the relationship between diet soda drinkers and obesity. You ask 30 people two questions: 1) "How many diet sodas did you drink in the past week?" and 2) "How many pounds overweight are you?" You compute a Pearson correlation between the answers to your two questions, and find that r = .65. 

Is the correlation significant at a two-tailed α of .05?
