Using traditional methods it takes 93 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 110 students, the researcher decides to reject the null hypothesis at a 0.05 level of significance.
What is the conclusion?
A. There is not sufficient evidence at the 0.05 level of
significance that the new technique lengthens training time.
B. There is sufficient evidence at the 0.05 level of significance
that the new technique lengthens training time.
From the given information,
As null hypothesis rejected,
The required correct answer is,
B. There is sufficient evidence at the 0.05 level of significance that the new technique lengthens training time.
Thank you.

Using traditional methods it takes 11.4 hours to receive a basic driving license. A new license training method using Computer Aided Instruction (CAI) has been proposed. Set up the hypotheses to test the claim at the 0.025 level that the new technique lengthens the training time. State the null and alternative hypotheses for the above scenario.
Using traditional methods, it takes 96 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 with 290 students and observed that they had a mean of 95 hours. Assume the standard deviation is known to be 8. A level of significance of 0.05 will be used to determine if the technique performs differently than the traditional method. Find the value of the test statistic....
