Is there sufficient evidence to conclude that there is a statistically significant difference in mean weight between the different NYHA groups?3). Pretend for a moment that the resulting p-value was 0.02. Do we reject the null hypothesis in this case? Why or why not? If we were to reject the null hypothesis, we would conclude that there is sufficient evidence to suggest a statistically significant difference in mean weight between the NYHA groups. The NYHA variable has four levels: would we know which of the four NYHA group means gave the statistically significant result?arrow_forward
- What are the reasons for a biased samplearrow_forwardWhat are the various pros and cons of qualitative versus quantitative methods? Which do you prefer and why? Please provide the scholarly literature used.arrow_forwardIn this fictitious example of a cohort study, we found that in a factory of 3,000 workers, 1,000 workers were exposed to toxic substances, and 2,000 were not. During the study period, 800 of the exposed workers developed some type of lung disease, and only 40 of the non-exposed workers developed a lung disease. A. What is the incidence of lung disease among exposed workers? Use 1,000 as the multiplication factor and answer should be in whole numbers. B. What is the incidence of lung disease among non-exposed workers? Use 1,000 as the multiplication factor and answer should be in whole numbers.arrow_forward
