Looking at the coefficients, Significance F, and p values, you can conclude: Since the Significance F value is less than 0,05 then this equation does not explain average cost. Since the coefficient on Q has a p-value less than 0.05 and a t-statistic larger than the absolute value of 1,96, the Q variable is statistically insignificant, indicating we dona t experience economies of scale. Since the coefficient on Q2 has a p-value greater than 0,05 and a t-statistic smaller than the absolute value of 1,96 , the Q2 variable is statistically insignificant, indicating we donat Emt experience diseconomies of scale. All of the above are true
