Module 2, Week 2, gretl problem set 4

 

Use gretl and the dataset “Maternal and Infant Health Survey 2002” to answer the following questions.

 

1. Test the hypothesis that mean birthweight is different from 7 lbs.

 

2. Test the hypothesis that mean birthweight is less than 6.5 lbs.

 

3. Test the hypothesis that the proportion of female babies is different from 0.50.

 

4. Create a new variable named “smoke” that equals 0 if the mother did not smoke any cigarettes during pregnancy and equals 1 if the mother smoked at least one cigarette during pregnancy.  Test the hypothesis that mean birthweight differs between smokers and non-smokers.

 

5. Test the hypothesis that the variables “gender” and “induced” are related (i.e. not independent).

 

6. Test the hypothesis that mean birthweight differs across mother’s race.
