Using traditional methods it takes 10.6 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 17 students and observed that they had a mean of 10.4 hours with a variance of 2.25. Is there evidence at the 0.025 level that the technique reduces the training time? Assume the population distribution is approximately normal. Step 1 of 5: State the null and alternative hypotheses.
