ll A study investigated whether telephone follow-up had any effect (positive or negative) on the quality of life in patients with cancer. 70 subjects were enrolled and contacted by phone weekly to discuss medications and problems, and offer advice. The quality of life of each subject was assessed twice. once at enrollment, and once after 4 weeks. The assessment was done using the FACT-G, questionnaire that yields a number between 0 and 108 (larger numbers indicate higher well-being). The investigators want to show that there is a difference between the baseline and 4-week scores. The scores can be assumed to be normally distributed. The pvalue is 0.0003. Suppose that the investigators set the signicance level of the appropriate test at 5%. What is the conclusion of their test? Reject H0. There is a significant difference between the baseline and 4-week scores. 0 Reject H0. There is no significant difference between the baseline and 4-week scores. 0 Fail to reject H0. There is no significant difference between the baseline and 4-week scores. 0 None of these are correct. 0 Fail to reject H0. There is a significant difference between the baseline and 4-week scores
