(1 point) The distribution of study times for first year students follows a Normal distribution with standard deviation o = 51 minutes. Suppose a sample of 384 students found that the mean study time for these students was = 164 minutes per week. Use this to find a 85.09% confidence interval to estimate the mean study time for all students. We are 85.09% confident that the mean study time for first year students is between minutes and minutes. What is the margin of error for your confidence interval? Margin of error =
