Write answer in between .Q:A group of bariatric surgeons are investigating a novel surgically-placed tube that drains a portion of the stomach following each meal. They are interested in studying its efficacy in facilitating weight loss in obese adults with BMIs 40 kgm2 who have failed to lose weight through non-surgical options. After randomizing 150 patients to undergoing the surgical tube procedure and 150 patients to non-surgical weight loss options e.g., diet, exercise, the surgeons found that, on average, participants in the surgical treatment group lost 15 of their total body weight in comparison to 4 in the non-surgical group. Which of the following statistical tests is an appropriate initial test to evaluate if this difference in weight loss between the two groups is statistically significant?? A: Paired two-sample t-test, B: Kaplan-Meier analysis, C: Multiple linear regression, D: Pearson correlation coefficient, E: Unpaired two-sample t-test,  <response>: This is a question asking about which statistical test is appropriate to compare the mean weight loss between two independent groups - a surgical treatment group and a non-surgical control group. The two groups were randomly assigned, so this is an experimental design with independent groups. We want to compare the mean weight loss between these two independent groups, so an unpaired two-sample t-test is the appropriate statistical test.E: Unpaired two-sample t-test
