question 23 of 25\nthe nurse is conducting a study on the effectiveness of nursing interventions to prevent hospital - acquired infections. which aspect of the study design will help prevent a type ii error?\nusing a small sample size\nsetting the alpha level at 0.01\nsetting the power level at 0.70\nmaximizing variables examined
Answer
# Brief Explanations:
A Type II error is the failure to reject a false null hypothesis. Power is the probability of correctly rejecting a false null hypothesis (1 - β, where β is the probability of a Type II error). Increasing the power level reduces the chance of a Type II error. A higher power level means a greater ability to detect a true effect. Using a small sample size decreases power. Setting a very low alpha level (0.01) makes it harder to reject the null hypothesis and doesn't directly prevent Type - II errors. Maximizing variables examined can increase complexity and noise, not prevent Type - II errors.
# Answer:
Setting the power level at 0.70
