An automatic merge system has been installed at the entrance ramp to a major highway. Prior to the installation of the system, investigators found the average stress level of drivers to be 8.2 on a 10-point scale. After installation, a sample of 50 drivers showed a mean stress level of 7.6 with a standard deviation of 1.8. Conduct a hypothesis test using a significance level of 0.01 to determine if the average stress at peak hours for drivers under the new system is less than 8.2.
