Suppose you were interested in testing the relationship between type of drug and relief from head ache. For this example, assume you had counts of the number of persons taking two drugs (say, Aspirin and Tylenol) and their subsequent response in terms of headache was coded into two groups: "went away after taking the drug" or "did not go away". In this case, would you use a chi-square test of goodness of fit or a test of independence? A. Goodness of fit B Test of independence

option B is correct

Step-by-step explanation:

since here we want to see if there is a relationship between two variables (taking different drug and headache levels_)

option B is correct

B. test of independence

B, sometimes

Step-by-step explanation: Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion .
