1. Ten male volunteers were transported to a simulated altitude of 8000 m and given a variety of activities to complete as part of a study looking at the effects of alcohol on the human body at high altitude. Each participant was closely monitored for performance decline brought on by oxygen deprivation, and the number of seconds of usable awareness was kept track of. The experiment was repeated three days later, one hour after the same ten participants had unintentionally ingested 1 ml of 100%proof alcohol per 5 kg of body mass. Once again, the number of seconds of useful awareness was noted. The hypothesis that there is a noticeable change in the useful awareness at high altitude is one that the researchers would want to investigate. a. TRUE OR FALSE: For the parametric test to be valid, the data on men's useful consciousness before and after consuming 1 ml of 100%-proof alcohol per 5 kg of body mass should be independently checked for normality. b. TRUE OR FALSE: The acceptable alternative hypothesis (in symbols} is p before :5 p_after if the non-parametric test will be employed to examine the claim. c. Consider if one of the parameters for the parametric test was not fulfilled. The proper test technique to use is _____ . d. If the tests p-value was 0.05, we would ____ Ho. So, at a 10% level of significance. there is ______ evidence to say that the average useful consciousness before and after drinking 1 ml of 100%-proof alcohol per 5 kg of body mass is different. i. reject; sufficient ii. Reject; insufficient iii. Fail to reject; sufficient iv. Fail to reject: insufficient
