Students in statistics classes were asked whether they preferred a 10-minute break or to allow them go out of class 10 minutes early. In a sample of 150 students, 40 preferred a 10-minute break, 80 preferred going out 10 minutes early, and 30 had no preference. We want to determine if there is a difference in students' preferences. The p-value for testing the hypotheses is
A) less than .002.
B) between .002 and .05.
C) between .05 and .10.
D) greater than .10.
