The Department of Physiology is currently conducting a study investigating the use of redbull vs coffee consumption prior to the exam period. Conducted over a period of 4 weeks, participants are asked to consume either red bull or coffee every second day. Performance is measured from the PHY3171 exam results. (Assume the data is normally distributed, there are 50 participants in each group)

Which of the following is the correct statistical analysis to perform to determine whether red bull or coffee is more effective to improve exam performance (comparing exam performance between both groups)?
