Suppоse а teаm оf reseаrchers cоnducts a randomized controlled trial in which they randomly assigned individuals to either a Mediterranean diet or no diet. After a year they assessed the fasting blood glucose levels of all individuals. Suppose that the mean difference in the fasting blood glucose levels was -22 milligram/deciliter, indicating that individuals with the Mediterranean diet had a lower blood glucose level than individuals who did not follow a specific diet. Also suppose that the p-value for the null hypothesis significance test was 0.01. Is there a statistically significant difference at alpha 0.05 in the fasting blood glucose levels between the two compared groups (yes/no)? (2 points) Explain why you think that there is/is not a statistically significant difference at alpha 0.05 (2 points).
