When subjects were treated with a drug, their systolic blood pressure readings (in mm Hg) were measured before and after the drug was taken. Results are given in the table below. Assume that the paired sample data is a simple random sample and that the differences have a distribution that is approximately normal. Using a 0.05 significance level, is there sufficient evidence to support the claim that the drug is effective in lowering systolic blood pressure? Before: 188, 210, 157,...

Given: At normal temperature and pressure, the following conversion formulas may be used to convert back and forth between ppm and mg/m3 . mg/m3= [(MW x ppm) / 24.45] or ppm = [(24.45 x mg/m3 ) / MW] MW: molecular weight in g/mole In these equations 24.45 is the volume (in liters) of a mole (gram molecular weight) of a gas or vapor when the pressure is at 1 atmosphere (760 mmHg) and the temperature is at 25°C. When temperature...

The blood pressure at your heart is approximately 100 mm of Hg. As blood is pumped from the left ventricle of your heart, it flows through the aorta, a single large blood vessel with a diameter of about 2.5 cm. The speed of blood flow in the aorta is about 60 cm/s. Any change in pressure as blood flows in the aorta is due to the change in height: the vessel is large enough that viscous drag is not a...

21.HE.B: Captopril is a drug designed to lower systolic blood pressure. When subjects were treated with this drug, their systolic blood pressure readings (in mm Hg) were measured before and after the drug was taken. The results are in the accompanying table on the next page. (a) Go through “The Drill” for paired t-tests (Use a 0.05 α-level and the corresponding confidence interval.) The Drill: Assumptions and Conditions Paired Data Condition The data must be paired. Only use pairing if...

A resting systolic blood pressure (BP) of 120 mm Hg is stated to be the population mean for women. This was based on research conducted by several researchers on women from the healthy general public. Consider 20 first-year resident female doctors drawn at random. The resting systolic BP measured using an electronic sphygmomanometer are listed below. Is the sample significantly different from the population? State the null and alternative hypotheses Set the criteria for a decision: two-tailed test with a...
