Using traditional methods it takes 91 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 110 students and observed that they had a mean of 92 hours. Assume the population variance is known to be 36. Is there evidence at the 0.02 level that the technique lengthens the training time? State the null and alternative hypotheses.
