Let {X₁, X2,..., Xn} be the scores from Midterm 1 and {Y₁, Y2, ..., Ym}be those from Midterm 2. We assume that the scores in Midterm 1 are Normal (₁, 0) r.v.s andthose of Midterm 2 are Normal(2, 02) r.v.s. In addition, scores are independent r.v.s withinand between midterms. Our interest is to see whether there is a meaningful difference betweenthe (population) averages, i.e., ₁-2. The most intuitive estimator for the quantity of interestis X-Y. Let us assume that of and o2 are completely known constants. Find a 95% confidence-interval for 12, using the exact method (pivotal quantity). (Hint: if X~ N(μ₁,02) andY~ N(μ2, 02) and X and Y are independent, then X - Y ~ N(H₁-H₂,0² +03).)

Arsenic is a compound that occurs naturally in very low concentrations. Arsenic blood concentrations in healthy individuals are Normally distributed with a mean of 3.2 mg/dl. Some areas of the United States have naturally elevated arsenic levels in the ground and water supplies. Researchers took a sample 20 water samples from a particular area and measured the arsenic levels in each of the 20 water samples. They want to determine if there is sufficient evidence to conclude that the arsenic level in that area is higher than 3.2 mg/dl. hypothesis test for one population mean (unknown population standard deviation) confidence interval estimate for one population mean (unknown population standard deviation) hypothesis test for population mean from paired differences confidence interval estimate for population mean from paired differences hypothesis test for difference in population means from two independent samples confidence interval estimate for difference in population means from two…
