To determine if a protein powder helps athletes gain muscle mass, 10 volunteers are given capsules with a protein powder and 10 other volunteers are given capsules with a similar protein-free powder. After taking the capsules for 6 months, researchers measure the increase in muscle mass for each volunteer.
Explain what the researchers can do to minimize the change of a Type I error.
Instead of using a significance level of 0.05, the researchers could demand stronger evidence with a smaller significance level, such as 0.01.
Describe a drawback this action might have.
Demanding stronger evidence increases the probability of a Type II error.
Explain what the researchers can do to minimize the change of a Type II error.
Researchers could recruit more than 10 volunteers for each treatment.
Researchers could acceept evidence that is less convincing by using a larger significance level.
Describe a drawback this action might have.
This will take more time and cost more money.
Accepting weaker evidence increases the probability of a Type I error.
