City Police Number of Crimes
Oxford 15 17
Starksville 17 13
Danville 25 5
Holgate 17 7
Carey 12 21
Whistler 11 19
a. If we want to estimate crimes on the basis of the number of police, which variable is the dependent variable and which is the independent variable
b. Draw a scatter diagram
c. Determine coefficient of correlation
d. determine the coefficient of determination
e. Interpret these statistical measures. Does it surprise you that the relationship is inverse?
f. Determine the regression equation
g. Estimate the number of crimes for a city with 20 police
h. Interpret the regression equation
