X₁... Xin random sample size n for I group, Y.... Ym random sample size m in another group. Assume X & Y are mutually independent and follow NI Mx, 0%) & N ( My, og) (a) Assuming of 20% are known, snow the MLE of ratio 10 = My / Mx is ô = Y/X (b) Following (a), snow that & is a pirotal quantify where Q = 7-0X √ozy lm +6% of fin use this quantity to find an approximate (1-x) confidence interval for σ. Is it possible to find an exact confidence interval for o. (C) To compare Mx & My you can also construct a (1-x) confidence interval for n = My - Mx- Find the confidence interval exactly or approximately, and say it that interval is better than the one in D
