UNSW is recently focused on the student experience and wants to ensure that its students are coping. A key metric is to ensure that the failure rate remains below 30% for all its courses. Based on their experience, UNSW believes that the failure rate is 25% for its courses and fits a normal distribution with a standard deviation of 5%.

Suppose that the UNSW does not want to change the mandated failure rate of 20%. To ensure that it meets its target (i.e. less than 1% of all its courses has a failure rate of less than 30%). What is the largest standard deviation UNSW can tolerate to ensure that it meets its targets? (Choose the closest answer)
