Given the following paritalminitab printout of the number of police
1- Given the following paritalminitab printout of the number of police officers present in a particular area of a city and the number of crimes committed during that time, answer the following questions: Correlations: No. of Police Officers, No. of Crimes Pearson correlation of No. of Police Officers and No. of Crimes = -0.912 Regression Analysis: No. of crimes versus No. of Police Officers The regression equation is No. of Crimes = 22.2 - 1.54 No. of Police Officers What is the correlation value "r"?
-0.912 If 8 police officers are present, predict the number of crimes that would occur. (round the nearest crime)
10 Based on your correlation coefficient, how good (valid) is your prediction, poor, okay, good, very good?
Very good For each additional police officer, what would you predict the increase or decrease in the number of crimes be? (use + for increase and - for decrease and give the value round to 3 decimal places)
