University officials hope that changes they have made have improved the retention rate. Last year, a sample of 2088 freshmen showed that 1580 returned as sophomores. This year, 1524 of 1941 freshmen sampled returned as sophomores. Determine if there is sufficient evidence at the 0.05 level to say that the retention rate has improved. Let last year's freshmen be Population 1 and let this year's freshmen be Population 2. Step 1 of 3: State the null and alternative hypotheses for the test. Fill in the blank below.

Using traditional methods it takes 101 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 lengthen training time and decides to perform a hypothesis test. After performing the test on 170 students, the researcher fails to reject the null hypothesis at a 0.10 level of significance. What is the conclusion?
