Write out an equation for the estimated demand function2. Interpret the signs and values of all the estimated coefficients.3 Using the t-tests determine which coefficients are non-zero.4. Compute the price elasticity, cross price elasticity and income elasticity of Pizza.5. How confident are you that the sample used in this exercise is a good fit for the entire population?
