Using traditional methods it takes 104 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 70 students and observed that they had a mean of 105 hours. Assume the population standard deviation is known to be 6. Is there evidence at the 0.05 level that the technique lengthens the training time? Step 2 of 6 : Find the value of the test statistic. Round your answer to two decimal places.
