You are a sports analyst in a major TV sports network. Michael, your manager, wants you to analyze the NBA data stats from the 2021-2022 NBA season. A sample of players and their individual stats are provided in the Excel file NBA 2021 2022 Regular Season data.xlsx The data dictionary can be found on the following page: https://en.m.wikipedia.org/wiki/Basketball_statistics.

Michael would like you to answer the following questions. He also wants a report based on your data analysis and conclusions. 1. Is there enough evidence that the usage rate (USG) of NBA players is less than 20%?

2. At a 5% level of significance, is there a difference between the average number of points scored by drafted vs undrafted players?

3. Construct a model to predict the number of points scored by a player (PTS) based on the number of games played (GP), the number of rebounds (RB), the number of assists (AST) and the conference they played in. What conclusions can be derived from the significance of the independent variables and the interpretations of the slopes?
