Please i need the executive summary format answer to this questions. Six Sigma Quality at Flyrock Tires.

4. Now consider the case where extrusion is a Six Sigma process. In this case, the extruder output should have a standard deviation of 1.667 thou. What proportion of the rubber extruded will be within specifications in this case? 5. Assuming that operators will continue to take samples of 10 sheets each hour to check if the process is in control, what control limits should Dalglas set for the case when extrusion is a Six Sigma process? 6. Return to the case of the worn bearing in question 3 where extrusion produces a mean thickness of 403 thou when the setting is 400 thou. Under this condition, what proportion of defective sheets will the extruder produce (for the Six Sigma process)? Assuming the control limits in question 5, what is the probability that a sample taken from the extruder with the worn bearings will be out of control? On average, how many hours are likely to go by before the worn bearing is detected
