Question

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?

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.

Using traditional methods, it takes 93 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 160 students and observed that they had a mean of 92
hours. Assume the variance is known to be 64 . A level of
significance of 0.02 will be used to determine if the technique
performs differently than the traditional method. Find the value of
the test statistic....
