Posted by Lea on Monday, May 7, 2012 at 11:36pm.

A random group of customers at a fast food chain were asked whether they preferred hamburgers, chicken sandwiches, or fish sandwiches. The restaurant's marketing department claims that 40% of the customers prefer hamburgers, 46% of the customers prefer chicken sandwiches, and 14% of the customers prefer fish sandwiches. Is there evidence to reject this hypothesis at a=0.05?

A) There is not evidence to reject the claim that the customers preferences are distributed as claimed because the test value 7.815<13.861
B) There is evidence to reject the claim that the customers preferences are distributed as claimed because the test value 13.861>5.991
C) There is not evidence to reject the claim that the customers preferences are distributed as claimed because the test value 5.991<13.861
D) There is evidence to reject the claim that the customers preferences are distributed as claimed because the test value 13.861>7.815
