Using traditional methods, it takes 91 hours to receive a basic drivers license. A new license training method using computer aided instruction (CAI) has been proposed. A researcher used the technique with 40 students and observed that they had a mean of 88 hours. Assume the standard deviation is known to be 7. A level of significance of 0.1 will be used to determine if the technique performs differently than the traditional method. Find the value of the test statistic. Round your answer to 2 decimal places.
