Question

A Wall Street Journal article reported that 15 of the 30 NBA teams have employees whose sole responsibility is to analyze data. The information compiled by these “statheads” is then used to help make decisions during games, for the draft, and to evaluate potential trades. At the time of the article’s writing, the 15 teams had played a total of 962 games and had won 570 of them.
a. Using σ = 0.01, can it be concluded that teams who employ “statheads” (I confess I am not really thrilled with this word) have an advantage over those teams that do not?
b. Verify your results using PHStat.
c. What concerns might you have with using a hypothesis test in this situation?
