The attached file has either 1 or 0 entries for over 160 students and across 14 classes. It is 1 if a student is called her/his name in a class and 0 otherwise.
Please test if each student is called his/her name with probability 0.2 (i.e., 20%) independently across students and classes, at 5% significance level.
Do not assume that there is a unique solution.
