For each of the following situations, indicate what the general impact on the Type II error probability will be: The alpha level is increased. Choose the correct conclusion below. The \"true\" population mean is moved farther from the hypothesized popoulation mean. Choose the correct conclusion below. The alpha level is decreased. Choose the correct conclusion below. The sample size is increased. Choose the correct conclusion below.

Solution

a)

OPTION B: An increase in alpha will result in a decrease of Type II error probability.

This is because the critical value will go farther from the actual mean, so it is less probable.

*******************

b)

OPTION B: The probability of committing a type II error decreases.

This is because the critical value will go farther from the actual mean, so it is less probable.

*********************

c)

OPTION A: The probability of committing a type II error increases.

This is because the critical value will go nearer to the actual mean, so it is more probable.

********************

d)

OPTION A: The probability of committing a type II error DECREASES.

This is because the distirbution becomes narrower, so the critical value will go farther from the actual mean, so it is less probable.
