Question

In the summer of 2014, a popular magazine selected a random sample of its subscribers and invited them to vote on its website for their favorite sips of the summer. The results were reported as follows: drink A, 35%; drink B, 30%; drink C, 20%; and drink D, 15%. To test the claim that preference has changed after 5 years, the magazine conducted a similar survey and reported the outcome based on 1,600 randomly selected respondents. The votes for the favorite sips were, 560 for drink A; 440 for drink B; 350 for drink C; and 250 for drink D. Find the value of the test statistic for testing the appropriate hypotheses? Round your answers to the nearest ten-thousandth (4 decimals).
