Tina believes students in her class are more likely to complete the face test than those not in her class.

Here is the table

frequencies	Tina's class	not in Tina's class
completing the face test	3	8
not completing the face test	9	5

Question: Looking at the table without doing any hypothesis tests, do you suspect Tina's belief is correct? Why/why not? Do you believe the sample provided is representative of the population( all students in Uni )? Why/why not?
