A study might compare the rates of microbiologic cure of threedifferent antibiotics used for urinary tract infection, as shown inthe following table:
| Antibiotics 1 | Antibiotics 2 | Antibiotics 3 | Total |
Cure | 49 | 112 | 26 | 187 |
Not cure | 12 | 37 | 8 | 57 |
Total | 61 | 149 | 34 | 244 |
- Are the variables quantitative or qualitative?
- Which statistical test is appropriate to use on thesedata?
- What are the null & the alternative hypotheses, here? Use10% level of significance
- Carry out the hypothesis test(s) in question in above c.
Is there is a relationship between which antibiotic the patienttook and achieving microbiologiccure?
