level of significance The probability of making a Type I error when the null hypothesis is true as an equality the null hypothesis. In hypothesis testing, the tentative assumption about the population parameter is called: Which of the following describes a Type II Error? Accept H0 when H0 is false. Whenever the probability of making a Type II error has not been determined and controlled, only two conclusions are possible. We either reject H0 or: do not reject H0. ...
