Using traditional methods it takes hours to receive an advanced flying license. A new training technique using Computer Aided Instruction (CAI) has been proposed. A researcher believes the new technique may reduce training time and decides to perform a hypothesis test. After performing the test on students, the researcher decides to reject the null hypothesis at a level of significance.
What is the conclusion?
Solution:
First we write the null and alternative hypothesis for given problem.
Null Hypothesis H0 : = 107 Hours
Alternative Hypothesis : H1 : > 107 (lengthen training time)
Decision : reject the null hypothesis at a 0.10 level of significance.
So , conclusion is
At 0.10 level of significance . there is sufficient evidence to support the researcher 's claim that he new technique may lengthen training time
