You are testing the hypothesis that a new method for freezing green beans preserves more vitamin C in the beans than the conventional freezing method. Beans frozen by the conventional methods are known to have a mean Vitamin C level of 12 mg per serving, so you are testing 0 H versus:12 µ =:12 Ha µ >, where µ = the mean amount of vitamin C (in mg per serving) in beans frozen using the new method. You calculate that the power of the test against the alternative:13.5 Ha µ = is 0.75. Which of the following is the best interpretation of this value?

|
The complement of the probability of making a Type I error
|
|
|
The probability of concluding that the true mean is 12 mg/serving when it is actually 13.5 mg/serving.
|
|
|
The probability of concluding that the true mean is higher than 12 mg/serving when it is actually 12 mg/serving.
|
|
|
The probability of concluding that the true mean is 13.5 mg/serving when it actually 12 mg/serving.
|
|
|
The probability of concluding that the true mean is higher than 12 mg/serving when it is actually 13.5 mg/serving.
