Using traditional methods it takes 9.2 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 15 students and observed that they had a mean of 9.7 hours with a standard deviation of 1.3. Is there evidence at the 0.025 level that the technique lengthens the training time? Assume the population distribution is approximately normal. Step 4 of 5: Determine the decision rule for rejecting the null hypothesis. Round your answer to three decimal places.
