Solutions

Expert Solution

1. Type I error is when

C. we rejected a true null

Explanation:

We know that the type I occurs when we reject the null hypothesis when it is true.

2. Recall that for samples of a specific size randomly selected from a population, the means of the samples will vary about the...

e. population mean

Explanation:

We know that the unbiased estimator of the mean of the sampling distribution is the population mean.

3. Statistical evidence only supports the claim if it is ...

c. The null

Explanation:

We know that we take decision regarding the null hypothesis whether it would be rejecting or fail to reject.

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?
