g Using the previous part, find confidence intervals for α with asymptotic level 90% using both the "solving" and the "plug-in" methods. Use n=25 , and X¯¯¯¯n=4.5 . (Enter your answers accurate to 2 decimal places. Use the Gaussian estimate q0.05≈1.6448 for best results.)

An optical inspection system is used to distinguish among different part types. the probability of a correct classification of any part is 0.92. suppose that three parts are inspected and that the classifications are independent. let the random variable x denote the number of parts that are correctly classified. determine the probability mass function of x. round your answers to four decimal places (e.g. 98.7654). x f(x) 0 1 2 3
