sampling risk
type 1 errors-false rejection(related to efficiency)
test of controls (I/C)-risk of under-reliance on internal control.
substantive ($s)-risk of incorrect rejection of $ balance
sampling risk
type 2 errors-false acceptance (related to effectiveness)
I/C-risk of over reliance on internal control
Substantive-risk of incorrect acceptance of $ balance
nonsampling risk def
any mistakes made by the auditor other than having a sample that is not representative of the population.
