In early November 2019, Gallup conducted a national poll of 1015 U.S. adults that asked which country is the leading economic power in the world. Of those sampled, 538 said China. At the 0.01 level of significance, does the data provide sufficient evidence to conclude that, at the time, a majority (more than 50%) of U.S. adults consider China the leading economic power in the world? Solve using the p-value approach. a. Define the parameter we are testing and setup a hypothesis test to see if a majority of U.S. adults consider China the leading economic power in the world. b. Calculate the test statistics for this hypothesis test. c. What is the p-value for this hypothesis test?
