A biologist had mice and rats run through a maze and recorded the number that finished the maze successfully and the number that did not. This table lists the results of the study. At a = .05, test the claim that the rodent type and the success of finishing the maze are not related.

.........................Mice..........Rats
Finished.............30.............22
Did not Finish....36.............13

A) There is evidence to reject the claim that the rodent type and the success of finishing the maze are not related because the test value 9.488 > 1.393

B) There is not evidence to reject the claim that the rodent type and the success of finishing the maze are not related because the test value 2.773 < 3.841

C) There is not evidence to reject the claim that the rodent type and the success of finishing the maze are not related because the test value 1.393 < 9.488

D) There is evidence to reject the claim that the rodent type and the success of finishing the maze are not related because the test value 3.841 > 2.773
