Dr. Gary J. Gargano Merced College Psyc-05 Homework #13 Hypothesis Testing Never Ends! A sports psychologist is interested in determining whether the type of energy drink an athlete consumes can influence their running speed. A sample of 12 athletes are asked to run a 220 meter sprint after consuming an energy drink. On day 1, the athletes drink 8oz. of Red Bull then run a 220 meter sprint. Two days later, they come back and drink 8oz of Monster and then again run a 220 meter sprint. Assuming that weather conditions and all other variables remain constant, is there a difference in their running speed due to the type of energy drink consumed? The time to complete the sprint in seconds are listed below. Round all calculations to three decimal places.
