Question 1A paper company has about 50 paper mills distributed over 3 provinces. The 50 papermills have a totalof 600 machines. Lately it was found that some of the paper the company produces has a thicknessabove the specification of 2mm. From historical data it was found that the mean paper thickness 1.3mmthe variance of 2. Answer the following questions. 1.3. Find the estimated standard error of the proportion if, in the sample of machines, 36 machines hadproduced paper that is thicker than the average. Is this a good estimate?1.4. Find the estimated variance of the sample mean and its appropriate standard error. Explain youranswer.
