3. Application of Delta Method on Gamma Variables

(d) 0/4 points (graded) Using the previous part, find confidence intervals for a with asymptotic level 90% using both the "solving" and the "plug-in" methods. Use n = 25, and Xn = 4.5. (Enter your answers accurate to 2 decimal places. Use the Gaussian estimate q0.05 ~ 1.6448 for best results.) I solve = 4.172 4.828 I plug-in = 4.3275 X 4.3402 X STANDARD NOTATION
