The time taken by a student to finish a statistics exam can be modeled using the following cumulative distribution function: F(x) = 1-e, x>0 Suppose that the time taken for a student to finish the exam is constant from student to student. Then the mcan number (to the nearest whole nimber) of students who will finish the exam in less than 1 hour for 12 students randomly selected is equal to. O 6 None of the other options 8.
