Stress levels were recorded during a true answer and a false answer given by each of six people in a study of lie-detecting equipment, based on the idea that the stress involved in telling a lie can be measured. The results are shown below:

Use SPSS Output file attachedtoanswer the following questions (assume that stress follows a normal distribution and also the difference, use a 5% significant level): Test to see if the average stress levels are significantly different between the two Answers. If they are significantly different, are they significantly higher or lower when a false answer is given?

13.Conclusion: We reject null hypothesis and say that there is difference in stress between giving true and false answers and stress is higher when giving false answers

14.Conclusion: We do not reject null hypothesis and conclude that there is no difference in stress between giving true and false answers.

15.Conclusion: We reject null hypothesis and conclude that there is difference in stress between giving true and false answers and stress higher when giving true answers

16.Conclusion: We do not reject null hypothesis and conclude that there is difference in stress between giving true and false answers and the difference is higher when giving false answers.
