when describing Type I error under composite null hypothesis, the å usually we select the maximum of the probabilities, can anyone explain this concept for me?

here is an example given: Test H0: µ ≤ µ0 v.s. H1: µ > µ0, then the Type I error is described as å= max Pr[reject H0 | µ≤µ0] = Pr[reject H0 | µ=µ0]

how is this the maximum of the probabilities?

A Type 1 error is defined as: Rejecting a False Null Hypothesis Rejecting a True Null Hypothesis Failing to Reject a False Null Hypothesis Failing to Reject a True Null Hypothesis b.) The probability for which a Type 1 error may occur in a hypothesis test is referred to as: Z-value Test Statistic Critical Value Level of Significance c.) A researcher conducts a hypothesis test to evaluate the effect of a treatment. The hypothesis test produces a z-score of z...

When we reject a null hypothesis, we are certain that the alternative hypothesis is true. True or False

Select the statement that correctly describes a Type I error.

Select the statement that correctly describes a Type I error. A Type I error occurs when the null hypothesis is rejected when it is actually false. A Type I error occurs when the null hypothesis is accepted when it is actually false. A Type I error occurs when the null hypothesis is accepted when it is actually true. A Type l error occurs when the null hypothesis is rejected when it is actually true.

True or False section. When we reject the null hypothesis, we have proven the alternative hypothesis to be true. There are only two possible conclusions in a hypothesis test: reject or fail to reject the alternative hypothesis. A Type I error is made when a true null hypothesis is rejected. A Type II error is made when we fail to reject a true null hypothesis. The level of significance is the probability of making a Type II error. The probability...
