Using traditional methods it takes 96 hours to receive an advanced driving license. A new training technique using Computer Aided Instruction (CAI) has been proposed. A researcher used the technique on 100 students and observed that they had a mean of 95 hours. Assume the population standard deviation is known to be 7. Is there evidence at the .05 level that the technique performs differently than the traditional method?

1. State the null/alternative hypothesis

2. Value of the test statistic
