Question

A statistic controls _ by establishing the risk he or she is willing to take in terms of rejecting a true null hypothesis

Answer 1

Probability of type I error is the probability of rejecting H​​​​​​0  when it is true.

i.e, the error committed in rejecting the null hypothesis, when actually it is true, is called the type I error.

So our answer will be Type I error.

A statistic controls Type I error  by establishing the risk he or she is willing to take in terms of rejecting a true null hypothesis.
