    Your director has banned the use of all artificial fingernails, claiming their use contributes to patient infections in the unit. After multiple discussions the director has allowed you to do a research study to determine if the use of artificial fingernails causes increases in infection rates. You would really like to prove that their use does not contribute to infection rates. Without worrying about the research design in this case, or even how you might research it, state
    1. The null and alternate that you might use.
    2. What alpha you might use and why
    3. What rejecting the null would mean
    4. What failing to reject the null would mean
    5. What a type I error is in this case and the consequences of it?
    6. What a type II error is in this case and the consequences
    7. Which error is more important in this case.
