Using traditional methods it takes 105.0 hours to receive a basic flying license. A new license training method using Computer Aided Instruction (CAI) has been proposed. A researcher used the technique on 100 students and observed that they had a mean of 104.0 hours. Assume the standard deviation is known to be 7.0. Is there evidence at the 0.05
level that the technique performs differently than the traditional method?
