For numbers 5 to 7: As part of an investigation into the effects of alcohol on the human body at high altitude, ten male subjects were taken to a simulated altitude of 8000 m and given several tasks to perform. Each subject was carefully observed for deterioration in performance due to lack of oxygen, and the time, in seconds, at which useful consciousness was recorded. Three days later, the experiment was repeated one hour after the same ten subjects had unknowingly consumed 1 ml of 100%-proof alcohol per 5 kilograms of body mass. The time, in seconds, of useful consciousness was again recorded. The researchers would like to test the claim that there is significance difference in the useful consciousness at high altitude. 6. Suppose one of the assumptions for the parametric test was not satisfied. The appropriate test procedure to be used is

Suppose one of the assumptions for the parametric test was not satisfied. The appropriate test procedure to be used is O A. t-test for related samples O B. t-test for independent samples O C. Mann-Whitney U test O D. Paired Wilcoxon signed rank test

Which of the following is(are) TRUE? 1. The data on useful consciousness of men before and after consuming 1 ml of 100%-proof alcohol per 5 kg of body mass should be independently tested for normality for the parametric test to be valid. II. If the non-parametric test will be used to test the claim, the appropriate alternative hypothesis (in symbols) #after is before O A. I only B. II only O C. Both I and II O D. Neither I nor II
