At a high school, students can choose to enter through one of three doors. Custodians noticed that door #3 was always getting broken and suggested that more students use that door because it has a hands-free opener. Science minded students counted the number of students entering each door to see if the custodians were right.
The number of students to enter each door was counted; the data is summarized in the table below:
Choose the best statement:
A. The null hypothesis should be accepted.
B. The difference between the number of students who use each door cannot be explained by chance alone.
C. The difference between the number of students who use each door is due to chance alone.
D. There is no statistical difference between the number of students who use each door.
NOTE: I know that the answer is NOT A. The null hypothesis should be accepted.
