Using traditional methods it takes 94 hours to receive an advanced driving license. A new training technique using Computer Aided Instruction (CAI) has been proposed. A researcher used the technique on 120 students and observed that they had a mean of 92 hours. Assume the population standard deviation is known to be 8. Is there evidence at the 0.05 level that the technique reduces the training time? Step 4 of 6 Find the P-value of the test statistic. Round your answer to four decimal places.
