Answer:
(b) macaroni is categorized as an inferior good, and the price elasticity of supply is zero.
Explanation:
An increase in income by 10 percent results in a 15% reduction in the demand for macaroni and cheese without any change in price. This suggests that macaroni is indeed an inferior good with zero price elasticity of supply.
Inferior goods experience lower demand as incomes rise, supported by the observation that ‘’A 10 percent increase in income leads to a 15% decrease in the quantity of macaroni demanded’’.
In terms of price elasticity of supply, a value of zero indicates that the supply amount remains unchanged regardless of price fluctuations: the supply is "fixed". The original scenario states there was ''no change in the price of macaroni,'' indicating that the elasticity of supply in this situation is zero.
Within the regression model aimed at estimating monthly grocery spending based on family size, household income, and neighborhood characteristics, the "neighborhood" aspect functions as an independent variable. These independent variables serve as predictors, encompassing risk factors and confounding variables. The dependent variable in this scenario is the monthly household expenditures.
