Question The time taken by a student to finish a statistics exam can be modeled using the following cumulative distribution function: F(x) = 1-e-09*, x>0 Suppose that the time taken for a student to finish the exam is constant from student to student. Then the mean number (to the nearest whole number) of students who will finish the exam in less than 1 hour for 14 students randomly selected is equal to: O 6 O 8 O None of the other options O 7
