1) Write the estimated AVC (average variable cost) function. 2) Which regression coefficients are statistically significant at a 5% level?

1) Write the estimated AVC (average variable cost) function.

2) Which regression coefficients are statistically significant at a 5% level?

3) Which regression coefficients are statistically significant at a 1% level?

4) Test the hypothesis that all coefficients in the model except for the intercept are zero at a 1% level of significance.

5) Write the estimated SMC (short-run marginal cost) function.6) Do the signs of the coefficients of the estimated AVC and SMC functions appear to be correct? Why or why not?
