Using traditional methods it takes 104.0 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 on 70 students and observed that they had a mean of 105.0 hours. Assume the standard deviation is known to be 7.0. Is there evidence at the 0.02 level that the technique performs differently than the traditional method? Step 1 of 5: Enter the hypotheses: Keypad Answer 2 Points Keyboard Shortcut- Ho H
