MC Qu. 54 For a given sample size, when we increase th... For a given sample size, when we increase the probability of a Type I error, the probability of a Type II error:
remains unchanged.
increases.
decreases.
is impossible to determine without more information.

After testing a hypothesis regarding the mean, we decided not to reject H0. Thus, we are exposed to:
Type I error.
MC Qu. 56 After testing a hypothesis, we decided to re...
After testing a hypothesis, we decided to reject the null hypothesis. Thus, we are exposed to:
Type I error.
Type II error.
Either Type I or Type II error.
Neither Type I nor Type II error.
MC Qu. 57 Which statement about...
Which statement about is not correct?
It is the probability of committing a Type I error.
It is the test's significance level.
It is the probability of rejecting a true H0.
It is equal to 1 - .
Type II error.
Either Type I or Type II error.
Neither Type I nor Type II error.
Explanation / Answer
54 probability of type 2 error decreases. They move in opposite direction
55 type 2 error
56 type 1 error. It is committed when true hypothesis is rejected incorrectly
57 1-beta.the reason is this is called power of test rather than significance
