1. According to a recent report by PEW Research Center, dated on April 28, 2022, 62% of Americans say, “the relationship between China and Russia poses a very serious problem." Answer the problems Using the theory of simple random sampling of unweighted sample size of 3,581. Be sure to justify all steps both analytically and graphically. (a) Find the 96% confidence interval of the true proportion. (b) Is there sufficient evidence to declare more that 60% of Americans consider the rela- tionship between China and Russia poses a very serious problem? Set up the hypotheses and test them with the level of significance of a = 0.01. (c) Continued from Part (b), suppose that the true proportion is 62.5%. Find the ß value, the maximal conditional probability of type II error.
