explanatory variables in the factors will be retained. 6. Based on the results of the estimation in step 3‚ answer the following questions: a. How do you interpret the intercept‚ and the coefficient of the factors? First‚ the P value for this model is less than .05 so this model is significant. Then we can figure out the P value for each factor is significant‚ which means Factor 1‚ 2‚ 3 and 4 do have some effects on Price. Price=110.70+48.5*F1+33.49*F2+57.20*F3-8.30*F4 It means every unit increased

Let us examine the following condition of complete observations given above. Assume that $\Upsilon_{\chi}$ is taken as distribution function whose total failure times is studied using gamma distribution applied to the shape parameters $3$ together with scale parameters $2.$ On side of repair time it goes with the same way failure time with gamma distribution together with shape parameter $1‚$ and scale parameter $2$ respectively. The time $\tau$ is examined as the following $\tau=2.5‚\tau=5‚$ and

1) The model for the transportation problem consists of 18 decision variables‚ representing the number of barrels of wastes transported from each of the 6 plants to each of the 3 waste disposal sites: = Number of Barrels transported per week from plant ‘i’ to the j-th waste disposal site‚ where i = 1‚ 2‚ 3‚ 4‚ 5‚ 6 and j = A‚ B‚ C. The objective function of the manager is to minimize the total transportation cost for all shipments. Thus the objective function is the sum of the individual
