Question

Using traditional methods, it takes 11.8 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 16 students and observed that they had a mean of 12.0 horns with a standard deviation of 2.0. A level of significance of 0.1 will be used to determine if the technique performs differently than the traditional method. Find the value of the test statistic. Round your answer to 3 decimal places. Assume the population is normally distributed. Enter the value of the test statistic. Answer:______(Round your answer to 3 decimal places.)

Explanation / Answer

TEST STATIC = (12-11.8)/(2/SQRT(16))

= 0.4

THE DEGREE OF FREEDOM = 16-1 = 15

THE SIGNIFICANCE LEVEL = 0.1

FROM THE T TABLE THE P VALUE = 0.3473
