Using traditional methods, it takes 9898 hours to receive a basic driving license. A new license training method using Computer Aided Instruction (CAI) has been proposed. A researcher used the technique with 7070 students and observed that they had a mean of 9696 hours. Assume the standard deviation is known to be 66. A level of significance of 0.020.02 will be used to determine if the technique performs differently than the traditional method. Find the value of the test statistic. Round your answer to 2 decimal places.

Enter the value of the test statistic.
