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 180 students, the researcher decides to reject the null hypothesis at a 0.10 level of significance.

What is the conclusion?

Homework Answers

Answer #1

The null hypothesis, ho: new technique takes 93 hours to receive an advanced driving license. u = 93

An alternative hypothesis, h1: new technique takes more than 93 hours to receive an advanced driving license. u>93

At a 10% level of significance, the null hypothesis is rejected.

Hence the conclusion is that new technique takes more than 93 hours to receive an advanced driving license. u>93. thus there is sufficient evidence to support the claim that the new technique may lengthen training time At a 10% level of significance.
