Using the same anti-venom study, answer the following questions.

Researchers wanted to know the effectiveness of a new anti-venom.  A study was conducted on 150 children who had nonlethal scorpion stings.  The ages of the children ranged from 6 months to 18 years old.   Each child was randomly assigned to receive a shot of the anti-venom or a placebo shot.  Researchers recorded whether or not their condition improved over the next four hours.

a.  Identify the population for the study.


b.  Identify the sample for the study.


c.  Was this an observational study or a controlled experiment? Explain how you know.


d.  Assuming the rest of the study was well-designed, use the percentages you calculated in question 1 and the type of study conducted to discuss whether it would be reasonable to conclude that the new anti-venom is effective at treating nonlethal scorpion stings in children.
