Quizplus · Accepted Answer

Since there are four package designs, the expected frequency for each category would be 60/4 = 15. Therefore, the correct answer is C. A and B are not plausible because they are either too small or too large as expected frequencies for a random sample of 60. D could be a possible answer, but it is less likely because it assumes that only one design is preferred by all consumers.
