Question

6. Does taking antibiotics in childhood lead to weight gain later in life? Researchers analyzed data from nearly 164,000 children in the U.S., and found that about 21% of them received seven or more prescriptions for antibiotics during childhood. At age 15, those who received seven or more prescriptions for antibiotics at earlier ages tended to weigh about 3 pounds more, on average, than those who did not. (a) Identify as specifically as possible in this context: explanatory variable (b) Identify as specifically as possible in this context: response variable (c) Using only the information provided, do you think there is strong evidence to reject the appropriate null hypothesis? Answer YES or NO and explain without doing any calculations. (d) Using only the information provided, do you think the results were practically signifi- cant/important? Answer YES or NO and explain without doing any calculations. (e) One headline read "New Study Says Antibiotics Cause Weight Gain in Youth". Is this title appropriate for this study? Answer YES or NO, and explain how you are making your decision based on the information provided, using appropriate statistical terms in context. (f) Suggest a reasonable potential confounding variable, and explain why it is a potential confounding variable in the context of this study. If there are no confounding variables, explain why not.
