α type-II error, and its probability is α

α type-II error, and its probability is β

Which error is occurred when the defendant were found guilty if, infect the defendant is innocent

Choose an answer

type-I

type-II

no error

both a and b

A hypothesis that specifies all the value of parameter is called:

Choose an answer
