Suppose that 72.4% of all adults with type 2 diabetes also suffer from hypertension. After developing a new drug to treat type 2 diabetes, a team of researchers at a pharmaceutical company wanted to know if their drug had any impact on the incidence of hypertension for diabetics who took their drug. The researchers selected a random sample of 500 participants who had been taking their drug as part of a recent large-scale clinical trial and found that 353 suffered from hypertension.
The researchers want to use a one-sample z-test for a population proportion to see if the proportion of type 2 diabetics who have hypertension while taking their new drug, p, is different from the proportion of all type 2 diabetics who have hypertension. They
decide to use a significance level of a = 0.01.
Determine if the requirements for a one-sample z-test for a proportion been met. If the requirements have not been met, leave the rest of the questions blank.
