(adapted from Johnson, 1980) Each semester, there are seven sections of a particular biology course, taught at various times by various instructors. The table below shows the number of students who selected each of the seven sections in Fall 2016. Do the data suggest that students have a preference for certain sections of the course? Perform a test of hypothesis using a = 0.05. In answering, be sure to address each of the five steps in a test of hypothesis. Number of students 1 18 2 12 3 25 Section 4 23 5 8 6 19 7 14
