Researchers conducted an experiment to evaluate the effectiveness of a new weight loss drug. Participants were randomly assigned to either the experimental group or the control group. Both groups took a pill every day. For the participants in the experimental group, the pill contained the weight loss medicine. For the participants in the control group, the pill did not contain the weight loss medicine. Each group took the pill for 12 months At the end of the 12 months, results indicated that the experimental group had lost more weight than the control group. Women in the experimental group had lost an average of 15 pounds during the study. Women in the control group had lost an average of 14 pounds during the study. The t test indicated that there was a 3% probability that this difference between the two groups was due to chance. Is the difference between the two groups clinically significant
