Sing traditional methods, it takes 108108 hours to receive a basic driving license. a new license training method using computer aided instruction (cai) has been proposed. a researcher used the technique with 110110 students and observed that they had a mean of 107107 hours. assume the standard deviation is known to be 77. a level of significance of 0.020.02 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. enter the value of the test statistic.
