Information Regression Results interpretation: Use the following information to answer questions 1 An interesting paper, Crime on the Court" by McCormick and Tollison investigates the effect that the switch from two to three referees in basketball had on the number of fouls calLed in a game. For example, with more referees calling the game players may commit fewer fouls out of fear of being caught. They used data from the ACC conference from 1954 to 1983. In 1978 the league switched from 2 to 3 referees. Here are some regression results from their paper. In the table HITEDIFF measures the difference in height (in inches) between teams, SCORE measures the total score,ATTEND measures the attendance and OFFICIAL measures the number of officials (i.e. referees).

15 ) dependent variable is number of fouls in the game
Option d) is correct
16) author want to test that when we increase number of refree , the number of foul reduces
Hence option D) is correct
17) when the number of refrees is increase from 2 to 3
The number of fouls decrease by 21
As coefficient of official is -21.059
Change in official = 3-2 = 1
Hence -21 *1 = -21
Hence option d) is correct
18)
Yes ,as p-value = 0.001 which is less than 0.01
Hence option B) is correct
