A researcher is studying the distribution of blood types in a population. The expected distribution based on previous studies is as follows: 40% Type O, 10% Type AB, 40% Type A, and 10% Type B. The researcher collects data from 200 individuals in a new study. In a separate study, the same researcher wants to investigate whether there is an association between blood type and reaction to a specific medication (No Reaction, Mild Reaction, Severe Reaction). The researcher collects data on the blood type of each participant and their types of reactions. Which statistical test is most appropriate in this scenario? Choice 1 of 4:C. Chi-squared test for goodness of fit Choice 2 of 4:D. Chi-squared test for independence Choice 3 of 4:B. Two-sample z-test Choice 4 of 4:A. Two-sample t-test
