is the statistical significance test the same as p value when using p value what is the importance what is the difference between the probability function and the power function in r what is the power function in r what is the significance of the power in r why rely on p value r why would you use pvalue what is the power function in r can the p-values be used to evaluate a hypothesis? what is the power function in r? is p value an alternative to p value what is the importance of the power function in r why does p value in r need a p value which method best describes the importance of using a p-value in r is the power function a p value r what is power function what is the alternative to p value in r what is p value used for what is the purpose of the power function and the expected loss function why use p value for statistical inference
