From a nationwide study, we know that the mean diastolic blood pressure is 60 mm gH for children aged 5-6 years of age, and that the measurements are normally distributed. Blood pressure measurements were taken on 13 children aged 5-6 years living in a specific community to determine whether their living conditions resulted in a difference in mean blood pressure. For these children the average diastolic blood pressure was found to be 55 mm Hg with standard deviation 7.5 mm...

Research Scenario Hypertension is defined as a systolic blood pressure (SBP) of 140 mmHg or more, or a diastolic blood pressure (DBP) of 90 mmHg or more. Diastolic blood pressure (DBP) measurements from the general population form a normal distribution with m = 82 mmHg and s = 10 mmHg. Epidemiological studies have shown that obesity increases the risk of hypertension (high DBP). Using data from a cohort study, a researcher obtained a sample of n = 144 obese persons...

A new drug, Zia, is being tested for lowering blood pressure. The company claims that less than 10% of users experience side effects. In a clinical trial of 650 randomly selected patients who received Zia, 52 reported side effects. Is there evidence at the ∝= 0.05 significance level to support the company’s claim? a) State the null and alternative hypothesis b) Calculate the test statistic (by hand!) (2 decimal places) c) Reject or Fail to reject the null hypothesis? Why?...

A pharmaceutical company claims that its new drug reduces systolic blood pressure. The systolic blood pressure (in millimeters of mercury) for nine patients before taking the new drug and 2 hours after taking the drug are shown in the table below. Is there enough evidence to support the company's claim? Let d=(blood pressure before taking new drug)−(blood pressure after taking new drug)d=(blood pressure before taking new drug)−(blood pressure after taking new drug). Use a significance level of α=0.01 for the...

In a​ study, researchers wanted to measure the effect of alcohol on the hippocampal​ region, the portion of the brain responsible for​ long-term memory​ storage, in adolescents. The researchers randomly selected 1010 adolescents with alcohol use disorders to determine whether the hippocampal volumes in the alcoholic adolescents were less than the normal volume of 9.029.02 cm cubedcm3. An analysis of the sample data revealed that the hippocampal volume is approximately normal with x overbar=8.0cm3 and s=0.7cm3. Conduct the appropriate test...
