The National Hockey League reports that there is a difference in average weights for their
forwards compared to their defensemen.
Does the mean weight differ by position for forwards vs. defensemen for junior hockey league
players as well? A random sample of 80 junior hockey league players in 2018 (48 forwards and
32 defensemen) was taken, and their position and weight were recorded. A test for the
difference of two means will be performed at a 5% significance level.
