The distribution of majors at the college is shown below. Major Math/Science Arts and Humanities Business and Economics Others Percents 24 33 34 9 Suppose a random sample of 400 athletes from the college are surveyed. The table below shows the results of the survey. Major Math/Science Arts and Humanities Business and Economics Others Frequency 95 146 118 41 What can be concluded at the 0.05 level of significance? Perform the hypothesis test. H0: The distribution of majors for athletes at the college is the same as the distribution of majors for the general population.
