Question

A pharmaceutical company is trying to determine if a new drug is more effective than the current standard drug. The company tracks random samples of patients on each drug and calculates the proportion that see an improvement in symptoms after six months. The results of the data collected are shown below. What are the population parameters? Pick New drug Successes 261 Observations 300 p-hat_1 0.870 Old drug Successes 419 Observations 500 p-hat_2 0.838 Confidence Level 99% z-score 1.227 p-value 0.1094 What is the level of significance? Ex: 0.12 What is the null hypothesis H0? Pick What is the alternative hypothesis Ha? Pick Should H0 be rejected or does H0 fail to be rejected? Pick What conclusion can be drawn from the data? Pick evidence exists to support the claim that more patients on the new drug see improvements in symptoms than patients on the current drug.
