Hypothesis 1: Head circumference at birth, length of the baby at birth, and weight of the baby at birth will all be associated.

For Hypothesis 1, identify the variables, their measurement level (e.g., nominal), and (if applicable) whether these are independent or dependent variables.

Then, state which analysis you will conduct (either one sample t test, paired t test, two sample t test, ANOVA, chi squared, correlations test, simple linear regression, or multiple linear regression test) and describe the important assumptions for this analysis.
