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 following data show values for these statistics for a random sample of 20 pitchers from the American League for one full season.

Student Name: A. The ages (in years) of 10 men and their systolic blood pressures (in millimeters of mercury) are shown in the data table below Systolic blood Age pressure 16 109 256 11,881 1,744 14,884 2,928 24 122 576 37 143 1,369 20,449 5,291 44 130 1,936 16,900 5,720 49 200 2,401 40,000 9,800 65 185 4,225 34,225 12,025 69 199 4,761 39,601 13,731 17,161 4,061 31 131 SE SAY 58 175 3,364 30,625 10,150 22 117 484 13,689 2,574 415 1,511 20,333 239,415 1. Complete the table 2. Use the table in 1) to find the coefficient of correlation between the variables age of men (X) and their systolic blood pressure (Y). 3. Find the coefficient of determination. (10(68024) -(415*1511))2 r2 = (10*20333-415squared) (10*239415-1511squared) = 0.818744 4. Interpret the coefficient of determination. R2 is 81.874% of systolic bp is justified by age. 5. Find the coefficient of alienation. =1-r2 =1-0.818744 =0.181256 6. Interpret the coefficient of alienation. =0.181256% of the systolic bp is not justified…
