Question

1). The p-value for this test is . 072. Do we reject the null hypothesis?
2). 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?
