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.
Answer with its Explanation:
The initial step is to ensure a diverse sample size that incorporates individuals from various cultures, geographic locations, religions, genders, and more, aiding in the optimal assessment of the product's market viability.
The second step involves determining a sample size to gather customer feedback within the required confidence interval that Burger King aims for. For instance, if Burger King targets a 93% customer satisfaction rate, the acceptable error margin can be established using the confidence interval. This sample size will be derived using a practical methodology.
The third step ensures that prediction errors remain reasonably low by implementing a practical method, confidence interval strategy, and diverse test samples. Altogether, this will provide the company with reliable data for informed decision-making.
