Major League Baseball (MLB) consists of teams that play in the American League and the National League. MLB collects a wide variety of team and player statistics. Some of the statistics often used to evaluate pitching performance are as follows:

  • ERA: The average number of earned runs given up by the pitcher per nine innings. An earned run is any run that the opponent scores off a particular pitcher except for runs scored as a result of errors.
  • SO/IP: The average number of strikeouts per inning pitched.
  • HR/IP: The average number of home runs per inning pitched.
  • R/IP: The number of runs given up per inning pitched.

The data in the Excel Online file below show values for these statistics for a random sample of 20 pitchers from the American League for a season. Construct a spreadsheet to answer the following questions.

Complete the equation below for an estimated regression equation developed to predict the average number of runs given up per inning pitched (R/IP) given the average number of strikeouts per inning pitched (SO/IP) and the average number of home runs per inning pitched (HR/IP) (to 3 decimals). R/IP=SO/IP++HR/IP a. Use the F test to determine the overall significance of the relationship. Compute F test statistic (to 2 decimals). The p-value is (to 3 decimals). What is your conclusion at the .05 level of significance? Use the t test to determine the significance of each independent variable. Compute the t test statistic for the significance of SO/IP (to 2 decimals). The p-value is (to 3 decimals). What is your conclusion at the .05 level of significance? Compute the t test statistic for the significance of HR/IP (to 2 decimals). The p-value is (to 3 decimals). What is your conclusion at the .05 level of significance?
