Using traditional methods it takes 98 hours to receive an advanced driving license. A new training technique using Computer Aided Instruction (CAI) has been proposed. A researcher believes the new technique may reduce training time and decides to perform a hypothesis test. After performing the test on 230 students, the researcher fails to reject the null hypothesis at a 0.02 level of significance. What is the conclusion?
