Description: I need help solving A certain drug can be used to reduce the acid produced by the body and heal damage to the esophagus due to acid reflux. The manufacturer of the drug claims that more than 94% of patients taking the drug are healed within 8 weeks.

Given that, x=226,n=239 Because np0(1-p0)=239×0.94×(1-0.94)=13.4796≈13.5>10, the sample size is less than 5% of the population size and the sample can be reasonably assumed to be random and the requirements for testing the hypothesis are satisfied. The sample proportion is,The value of test statistic is, Thus, the value of test statistic is, 0.36Critical value: By using the standard normal table of Z, the critical value at 95% confidence level for right tailed test Since the test statistic value (0.36) is less than critical value (1.65), then do not reject the null hypothesis at 5% significance level. Conclusion: Do not reject the null hypothesis. There is insufficient evidence to conclude that more than 94% of patients taking the drug are healed within 8 weeks
