Need help with the following last two questions- see numbers 1 and 2 at the bottom.

See the chart I've already completed.

Table 1: Characteristics of Women According to Intake of Alcohol

Note: intake of alcohol was during pregnancy except for pre-pregnancy BMI comparison where drinking status was also pre-pregnancy.

*Continuous variables presented by mean + standard deviation, categorical variables as %

** Test statistic is either a c² value or a t-value

1. What is the written answer to each of the four research questions in the matrix? What is being compared, what group or groups did better, and how much? Also, state if the difference was statistically significant or not.
2. Where the values of BMI more varied among the women who drank or did not drink prior to getting pregnant? Explain how you know this.
