Activity: Students participating in a psychology experiment on memory attended several lectures on their major area and were given an exam. Every month for a year after the exam, the students were retested to see how much of the material they remembered. The average scores for the group are given by the human memory model f(t) = 75 - 6 In(t+1), 0 Sts 12, where t is the time in months. Find the time passed in months) since the original exam if the average score at the current unknown time is 63.
