Using traditional methods it takes 106 hours to receive an advanced flying license. A new training technique using Computer-Aided Instruction (CAI) has been proposed. A researcher used the technique on 50 students and observed that they had a mean of 104 hours. Assume the population standard deviation is known to be 7. Is there evidence at the 0.02 level that the technique performs differently than the traditional method?   Step 4 of 6 :   Find the P-value of the test statistic. Round your answer to four decimal places.
