Following taking BA2551, he wanted to apply statistics to develop insights on where the team could improve in the next season to win the championship next year. Brad collected data online for team statistics across the NCAA to predict Wperc=win percentage. Brad’s independent variables include: Team=team name, Age=average age of members playing on the team, Wt=average weight of members on the team, ShPerc=shooting percentage of the team, SVPerc=save percentage of the goalie on the team. To complete this questions, download Brad's collected data set: hockey.csv Make sure to import into R studio to do your calculations.
Brаd’s cоаch preаches that a healthy diet is critical because teams with lighter, faster players win mоre games. What regressiоn Brad should run to validate this claim from their coach. Does the regression support this claim at the .05 significance level? variables are: The dependent variable is Wperc=win percentage. Brad’s independent variables include: Team=team name, Age=average age of members playing on the team, Wt=average weight of members on the team, ShPerc=shooting percentage of the team, SVPerc=save percentage of the goalie on the team.
