Using traditional methods, it takes 10.0 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 26 students and observed that they had a mean of 10.4 hours with a variance of 2.89. A level of significance of 0.1 will be used to determine if the technique performs differently than the traditional method. Assume the population distribution is approximately normal. Find the value of the test statistic. Round your answer to three decimal places.

Expert Solution

Solution-

We have given

Sample size = 26

Sample mean =10.4

Sample variance = 2.89

By provided information step by step t test is performed-

by above test results

we have not enough evidence to claim that a researcher used technique performs differently than the traditional method.

that is

technique does not performs differently than the traditional method.
