Question

The hockey season is wrapping up, and the Dallas Stars are trying to get into the playos. As of this writing, they have accumulated 84 points in 76 games. (A team earns two points for a win, none for a loss, and one for an overtime loss.) Treating the results thus far as a sample of the entire season, we have that they average 1.105 points per game with a variance of 0.922. Construct a 90% condence interval on the actual average number of points per game the Dallas Stars earn. Further, if the Stars need 110 points to win the conference, they need to average 1.341 points per game. Based o of your results, is it possible for the Stars to win the conference? Justify your answer. Lastly, discuss the validity of your results by checking and addressing all assumptions.
