An unconfined compression test was performed to determine the average strength of concrete cylinders (in psi). it is believed that the strength is approximately normally distributed with a standard deviation of 196 psi. a sample of 50 concrete cylinders was taken, and it was found that the average strength was 2500 psi. find a 92% confidence interval for the true average strength of the concrete.
