Osteoporosis is a degenerative disease that primarily affects women over the age of 60. A research analyst wants to forecast sales of Strong Bones, a prescription drug for treating this debilitating disease. She uses the model Sales = β0+ β1 Pop + β2lnc + ε, where Sales refers to the sales of Strong Bones ($ millions), Pop is the number of women over the age of 60 (in millions), and Inc is the average income of women over the age of 60 ($1,000s).

b. Interpret the slope coefficients.
c. Predict sales if a city has 1.5 million women over the age of 60 and their average income is $44,000.
