A yearbook company was investigating whether there is a significant difference between two states in the percents of high school students who order yearbooks. From a random sample of 150 students selected from one state, 70 had ordered a yearbook. From a random sample of 100 students selected from the other state, 65 had ordered a yearbook. Which of the following is the most appropriate method for analyzing the results?A. A one-sample zz-test for a sample proportionB. A one-sample zz-test for a population proportionC. A two-sample zz-test for a difference in sample proportionsD. A two-sample zz-test for a difference in population proportionsE. A two-sample zz-test for a population proportion
