A new antibiotic has just been developed, and scientists want to determine whether it is more effective than the current drug being used. They develop a study and divide 20 participants equally into Group A (the new antibiotic) and Group B (the current drug). They measure the average bacterial colony count (in thousands) after treatment with the different antibiotics. The average colony count for Group A is 5.4 thousand unit (standard deviation, s = 0.4) and the average colony count for Group B is 6.4 thousand unit (standard deviation, s = 0.5). Given the information provided, which statistical test would be used to analyze these data?
