Using traditional methods it takes 11.4 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 23 students and observed that they had a mean of 11.0 hours with a variance of 3.61. Is there evidence at the 0.025 level that the technique reduces the training time? Assume the population distribution is approximately normal. Step 2 of 5: Find the value of the test statistic. Round your answer to three decimal places.
