A random sample of 13 students were asked how long it took them to complete a certain exam. The mean length of time was 105.5 minutes, with a standard deviation of 66.7 minutes. Find the lower bound of the 90% confidence interval for the true mean length of time it would take for all students to complete the exam. Round to one decimal place (for example: 108.1). Write only a number as your answer. Do not write any units.
