A health educator was interested in determining whether college students at her college really do gain weight during their freshman year. A random sample of 5 college students was chosen and the weight for each student was recorded in August (the beginning of the freshman year) and May (the end of the freshman year). Help with figuring out if the data below suggest that college students gain weight during their freshman year? The health educator wants to use a 0.05 significance level to test the claim.
