To test the effectiveness of a new drug, a researcher gives one group of individuals the new drug and another group a placebo. The results of the study are shown below. At the 0.01 level of significance, can the researcher conclude that the drug is effective? In other words, are the results independent of the method of treatment?

Medication Effective Not Effective

Drug 32 9

Placebo 12 18

This question is asking to test the relationship between variables, drug vs. placebo? So I would use the Chi Square Test?

What are the H0 and the Ha?

H0 The drug is effective ????????

Ha The drug is not effective ????????

Are the Effective data points the Expected values? And the Not Effective ones the Observed values?
