Calculate the price elasticity of demand for Kingston’s product. b. Calculate the cross elasticity of demand between Kingston’s product and the rival product. c. According to the consultant, 2 = 0.98 and the standard error of estimate is 0.001. If the number of observations is 94, comment on the goodness of fit of the regression. |
