Stephanie Albini, chief risk manager of Action Park, Illinois, has collected data on the number of accidents occurring on city property over the last 72 months. The mayor of Action Park thinks accidents occur at random, but Ms. Albini believes that statistical analysis of the data is in order before such conclusions can be made. Ms. Albini runs a regression using the number of accidents per month as the dependent variable (NAC). For the first independent variable, Ms. Albini collects data on total monthly snowfall in inches (SNOW), because she believes that snow and ice are important contributors to accidents. To get a sense of whether variations in spending on facilities maintenance might be a contributing factor, Ms. Albini includes total monthly facilities and maintenance spending as the second independent variable in the analysis (MSPEND). After analyzing these data, what should Ms. Albini tell the mayor?
