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 (max. 2 points).
Suppоse а grоup оf reseаrchers conducted а randomized controlled trial to determine if a safe sex intervention helped prevent chlamydia among college students. In total, 220 college students participated in the randomized controlled trial, of whom 106 were randomized to the intervention condition and 114 to the control condition. Participants in the intervention condition were offered an online educational module on safe sex practices. Participants in the control condition did not receive any specific resources on safe sex practices. After one year, the participants were asked to report if they had chlamydia at any point during follow-up. The data from this study are summarized in table 1. Table 1. Data from a hypothetical intervention aimed at preventing chlamydia among college students.

Suppоse а grоup оf reseаrchers аimed to determine if maternal infections during pregnancy could be a cause of cerebral palsy in American children. Cerebral palsy is a relatively rare disease, as about 3 children per 1,000 American children have cerebral palsy. The researchers decided to perform a case-control study with children aged 18 or younger and living in Hillsborough County as the population of interest. They included all children with cerebral palsy and a random sample of children without cerebral palsy. The researchers estimated an exposure odds ratio of 2.04. The researchers claim that their exposure odds ratio of 2.04 can be interpreted as an outcome risk ratio. Why can the exposure odds ratio be interpreted as an outcome risk ratio in this case? (max. 6 points).
