Question
Can someone please explain to me how to establish if something is significant and what the relationship is between the r-value and the p-value? The questions are below the chart as a guide for the what the questions are asking for.

Result:
Can someone please explain to me how to establish if something is significant and what the relationship is between the r-value and the p-value? The questions are below the chart as a guide for the what the questions are asking for.
4f). BMI is the only variable negatively significantly correlated with mitrial regurgitation.
4g). low BMI is correlated with worse severity of mitrial regurgitation. ( negative correlation)
High systemic HTN is correlated with worse severity of mitrial regurgitation ( positive correlation).
4h).
Significant variables are age, BMI, systemin HTN and CHI or MI.
4I).
Age is highly correlated.
Higher age is correlated with worse severity of mitrial regurgitation.( r=0.13).
