A researcher hypothesizes that freshmen, sophomores, juniors, and seniors are represented equally among students who volunteer as research participants. The researcher intends to test this hypothesis by selecting a sample of N = 40 research volunteers. For the chi-square test, the expected frequency for freshman is: 10 20 40 none
