A certain type of fiber optic cable transmits light a mean distance of 58 km. A research team wishes to investigate if a modification in the manufacturing process will increase the mean acceptable transmission distance. A sample of forty batches of cable produced under the new process are tested. The sample mean is 59.1 km with sample standard deviation 2.31 km. Assume the population is normally distributed. The p-value for the test is:
