# Question: Refer to Exercise 5 67 After a confrontation with the teachers

Refer to Exercise 5.67. After a confrontation with the teachers’ union, the state promised to make reimbursements within 60 days.

If we assume that these 40 resignations represent a random sample of the state’s future performance, estimate the mean reimbursement time using a 99% confidence interval.
