Metro City Police believe that the number of domestic disputes on any summer night is highly correlated with the temperature that night (the hotter the night, the more family fights there are). If the number of disputes can be forecast, the police department can use the results to allocate personnel. Research analyst Silvia Jones regresses the number of domestic disputes (Y) on the Fahrenheit-temperature at 4:00 in the afternoon (X). Interpret this regression for the Metro City Police.

sb = 1.5 Sy|x = 18 r2 = .81 N = 150
Forecast the number of disputes if the temperature is 95° at 4:00 p.m.
