In this case, the groups are independent because they had MI and nothing is going to change the fact that they suffered from MI.2.T=3.15 describes mental health. This value is significant because p value =0.002 which means there’s a 99.8% chance of this difference occurring.3.T=1.99 is significant because p value in this research is set as p < 0.05. The meaning of this result is that health functioning is better in men than women 12 months post MI.4.The t ratio that indicates the largest difference between the males and females post MI is mental health = 3.15. This ratio is significant because it has a p value of 0.002 which means there’s a 99.8% likelihood of this difference being true.
