The Minister of National Security in Trinidad and Tobago is interested in determining the factors that influence the number of crimes that are reported. You are tasked to develop a model using the appropriate variables. The following variables are utilized:
X1 = total overall reported crime rate per 100,000 residents
X2 = reported violent crime rate per 100,000 residents
X3 = % of people 25 years+ with 4 yrs. of high school
X4 = % of 16 to 19-year-olds not in high school and not high school graduates.
X5 = % of 18 to 24-year-olds in college X6 = % of people 25 years+ with at least 4 years of college

She uses the model Sales = β0 + β1Population + β2Income + ε, where Sales refers to the sales of StrongBones (in $1,000,000s), Population is the number of women over the age of 60 (in millions), and Income is the average income of women over the age of 60 (in $1,000s).
