Q7 Based on the various relevant factors, one wants to predict if a team is going to have a winning season. Develop a logistic regression for this purpose. Use the knowledge that you gained in Q5 in selecting the variables. (Do not include the number of wins in the model.) Interpret the meanings of the coefficients. Once you have developed a logistic regression model, assume some values of the variables in the model and calculate the probability of a team to have a winning season.
