A football coach claims that players can increase their strength by taking a certain supplement. To test the theory, the coach randomly selects 9 athletes and gives them a strength test using a bench press. The results are listed below. Thirty days later, after regular training using the supplement, they are tested again. The new results are listed below. Test the claim that the supplement is effective in increasing the athletes' strength. Use α = 0.05. Assume that the distribution is normally distributed.

The herbal supplement biloba ginko is advertised as producing an increase in physical strength and stamina. To test this claim, a sample of n = 27 adults is obtained and each person is instructed to take the regular dose of the herb for 45 days. At the end of the 45-day period, each person is tested on a standard treadmill task for which the average score for the population is µ = 18. The individuals in the sample produce a...

23.38 Football and brain changes. American football is a contact sport that can expose players to repeated head impacts. While most impacts do not lead to a medically diagnosed concussion, an increasing body of evidence suggests that repetitive subconcussive head trauma can also result in neurocognitive deficits. Researchers recruited young football players (mean age, 12 years old). The players wore sensor-equipped helmets during all practice and game events for an entire football season to record subconcussion exposure (computed as an...
