After reading this case study answer the following questions that are mentioned below. Case Study: In a groundbreaking drug trial aimed at enhancing people's vocal abilities, researchers have reported promising results that offer hope to aspiring singers. The study focused on evaluating the effectiveness of a new drug called MeloVoice in improving vocal performance and singing skills. The trial involved a diverse group of 200 participants with varying levels of singing proficiency. Participants were randomly assigned to two groups: the experimental group receiving MeloVoice and the control group receiving a placebo. Both groups received singing lessons. Over the course of six months, participants underwent training sessions and vocal assessments to evaluate the impact of the drug on their singing abilities. Upon analyzing the data, the researchers found the following outcomes. The mean improvement in singing ability among participants in the experimental group was 30% as opposed to 10% in the control group. The median improvement in singing ability was 27% for the experimental group and 25% for the control group. Interestingly, the data for the experimental group exhibited a bi-modal distribution. One group displayed a peak improvement at 20%, while the other group demonstrated a higher peak at 35%. The mode for the control group was 17. The standard deviation of the improvement in singing ability was 3 (SD=3). and the p-value obtained for this study was less than 0.05.
