Show transcribed image text A randomized trial tested the effectiveness of diets on adults. Among 43 subjects using Diet 1, the mean weight loss after a year was 2.7 Ib with a standard deviation of 5.7 lb. Among 43 subjects using Diet 2, the mean weight loss after a year as 0 8 lb with a standard deviat on o 6.2 Construct a 95% con den e interval estimate o the difference between the population means o no assume he p ulation standard deviations are e a ses here appear a ein the effectiveness of the two diets? Click the icon to view the table of critical values. Find the 95% confidence interval (Round to three decimal places as needed.) Does the confidence interval show that there is a difference in the effectiveness of the two diets? OA. No, because the confidence interval includes zero. O B. Yes, because the confidence interval includes zero. O C. No, because the confidence interval does not include zero. â—‹ D. Yes, because the confidence interval does not include zero.
