Using traditional methods it takes 101 101 hours to receive an advanced flying 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 190 190 students, the researcher decides to reject the null hypothesis at a 0.05 0.05 level of significance. What is the conclusion?

There IS sufficient evidence. ?
