Answer the following questions in regard to these prices and quantities:Using the Midpoints Formula, determine the coefficient of price elasticity for the firm's premium ice cream.
Are there certain seasonal differences in demand for ice cream that could taint the price elasticity analysis? Explain.
Is there potential for a tainted study because of changes in external variables over the course of the year? For example, its major competitor won a national award for the best regional ice cream value.
