A random sample of 30 alloy of TIN and LEAD contains, on average, 100 grams of LEAD with a standard deviation of 0.8 mg. Find the 95% tolerance limits that will contain 90% of the alloy contents for this type of alloy. Assume that the lead content is normally distributed. Solve properly with clear solutions.
