For each of these following situations determine whether the

For each of these following situations, determine whether the decision was correct, a Type I error occurred, or a Type II error occurred:

Solution

a)The probability of rejecting H0 when =15 is 0.90. Incorrect.

b)The probability of making a correct decision when =15 is 0.90. Correct- Power of a test.

c)The probability that H0 is true when =15 is 0.10. Incorrect- type I error.

d) The probability of making a correct decision when =15 is 0.10. Incorrect- Type II error.
