Using the provided dataset below, determine whether

Using the provided dataset below, determine whether the mean birthweight for infants differs significantly according to mothers’ smoking status by using a one way ANOVA in Stata. Make sure to include all 5 hypothesis testing steps in your writeup. If you found a significant difference, how might you determine which specific groups differ? Are there any potential problems with the method you have proposed?

Define the parameter of interest.

1. State the hypotheses

2. Determine the test statistic and p-value considering any necessary assumptions

3. Decide whether to reject or not reject the null hypothesis

4. Clearly state a conclusion in the context of the problem

5. Specific Comparisons: How would you figure out which specific groups differ?

Potential Problems: What are the potential problems with the method you have proposed to figure out which groups differ?
