Using traditional methods it takes 11.011.0 hours to receive a basic driving license. A new license training method using Computer Aided Instruction (CAI) has been proposed. A researcher used the technique on 2525 students and observed that they had a mean of 11.411.4 hours with a variance of 1.961.96. Is there evidence at the 0.050.05 level that the technique performs differently than the traditional method? Assume the population distribution is approximately normal
