Question

Using traditional methods, it takes 104 hours to receive a basic flying license. A new license training method using Computer Aided Instruction (CAI) has been proposed. A researcher used the technique with 60 students and observed that they had a mean of 102 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. Round your answer to 2 decimal places. Enter the value of the test statistic.

Answer 1

Given, Mo=104, se=102, 6-8, 60, LA 105 Ho! M=104 HaiM & 104 The critical value for d = 0.05 and for two tailed test is ze=1196 test statistic 102404 za samo olun zo-1.936 B 160 Decision. Since it is observed that 12171.9362261.96 , it is theo coocluded that the oull. Hypothesis is Hypothesis is not rejected Conclusioni There is not enough evidence to claim that the technique performs differenty than the traditional method.
