Q1. Derive a control chart to test μ = 400 given that σ = 30 such that the (a) chances of a point going out of the control limits when the process really is in control are 1 in 20 while the chances of detecting a shift of μ to 425 within two samples after a shift occurs are 0.99 percent. For the same chart, what are the chances of detecting a shift of μ from 400 to 380 within two samples? 8 Define renewal process. Derive the renewal function. (c) Represent a general linear programming problem consisting of n variables and m constraints, in its canonical and standard forms. Given the following linear programming problem : Maximize z = x1 + 1.5x2 subject to the constraints 2x1 + 2x2 ≤ 160 x1 + 2x2 ≤ 120 4x1 + 2x2 ≤ 280 x1, x2 ≥ 0 find the solution of the problem using graphical method. 8 Define the pay-off matrix in a two-person zero-sum rectangular game. (d) Obtain a necessary and sufficient condition under which the game possesses a saddle point. 8 A study about a population showed that the mobility of the population of (e) a state to a village, town and city is in the following percentages : To From Village City Town Village 60 25 15 Town 10 70 20 City 10 30 60 What will be the proportion of population in the village, town and city after one year and two years, given that the present population has proportions of 0.50, 0.40 and 0.10 in the village, town and city respectively? 8 BJKE-B-STSC 2
