Suppose that 73.2% 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 1000 participants who had been taking their drug as part of a recent large-scale clinical trial and found that 718 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 ?=0.01 .
Determine the value of the z‑test statistic. Give your answer precise to two decimal places.
z=
Determine the p‑value for this test. Give your answer precise to three decimal places.

2. Researchers are evaluating a new drug for the treatment of Type II diabetes. They ran- domly assign 20 volunteers with a history of poor glucose control levels to two groups the Treatment group gets the experimental drug on trial, while the Control group re- ceives a standard drug. At the end of the clinical trial, participants have their A1C (glycated hemoglobin, a measure of long-term blood glucose levels) tested, the results are summarized in the table below Group A1C...

A pharmaceutical company has created a new drug to decrease how long patients suffer from a runny nose while having a cold. It is known that without treatment, on average, people report having a runny nose for 60 hours while having a cold. A test is organised for this new drug, hoping to prove the drug indeed decreases the duration of symptoms: 154 patients use it at the first sign of a runny nose...

11% of all Americans suffer from sleep apnea. A researcher suspects that a lower percentage of those who live in the inner city have sleep apnea. Of the 325 people from the inner city surveyed, 26 of them suffered from sleep apnea. What can be concluded at the level of significance of a = 0.05? a. For this study, we should use z-test for a population proportion b. The null and alternative hypotheses would be: Ho: D (please enter a...

2. Shelia's doctor is concerned that she may suffer from gestational diabetes (high blood glucose levels during pregnancy). There is variation both in the actual glucose level and in the blood test that measures the level. A patient is dlassified as having gestational diabetes if the glucose level is above 140 milligrams per deciliter (mg/di) one hour after a sugary drink. Shelia's measured glucose level one hour after the sugary drink varies according to the Normal distribution with μ-125 mg/dl...

please answer all the questi A patient admitted with type 2 diabetes asks the nurse what “type 2” means. What is the most appropriate response by the nurse? “With type 2 diabetes, the body of the pancreas becomes inflamed.” “With type 2 diabetes, the patient is totally dependent on an outside source of insulin.” “With type 2 diabetes, insulin secretion is decreased, and insulin resistance is increased.” “With type 2 diabetes, the body produces autoantibodies that destroy β-cells in the...

All the women were between 25 and 40 years old.
