Using traditional methods it takes 8.2 hours to receive a basicflying license. A new license training method using Computer AidedInstruction (CAI) has been proposed. A researcher used thetechnique on 26 students and observed that they had a mean of 8.0hours with a variance of 2.89 . Is there evidence at the 0.1 levelthat the technique reduces the training time? Assume the populationdistribution is approximately normal. Step 1 of 5: State the nulland alternative hypotheses.
