The Pearson correlation coefficient is the most suitable test for examining the relationship between maternal alcohol consumption and infant behavior. It will allow Ava to determine if there is a linear correlation between the two variables. The independent samples t-test and two-way ANOVA are not suitable in this case because they are used to compare means between two or more groups, and the dependent samples t-test is used when the same individuals are measured twice, which is not the case here.
