using traditional methods it takes 11.111.1 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 2626 students and observed that they had a mean of 10.910.9 hours with a variance of 1.441.44. is there evidence at the 0.0250.025 level that the technique reduces the training time? assume the population distribution is approximately normal. step 4 of 5 : determine the decision rule for rejecting the null hypothesis. round your answer to three decimal places.
