Consider the system of components connected as in the accompanying picture. Components 1 and 2 are connected in parallel, so that subsyslern works if and onlyif either 1 or 2 works; since 3 and 4 are connected in series, that subsystem works if and only if both 3 and 4 work. If components work independently of one another and P component i works 0.74 for , 1, 2 and-0.71 for ī-3, 4 calculate P ystem works). (Round your answer to...
photos for each question are all in a row (1 point) In the following questions, use the normal distribution to find a confidence interval for a difference in proportions pu - P2 given the relevant sample results. Give the best point estimate for p. - P2, the margin of error, and the confidence interval. Assume the results come from random samples. Give your answers to 4 decimal places. 300. Use 1.
