The drugs Telmisartan and Ramipril are designed to reduce high blood pressure. In a clinical trial to compare the effectiveness of these drugs in preventing heart attacks, patients were divided into three groups. One group took a telmisartan tablet daily, another group a rampipril tablet daily, and the third group too both.

A clinical trial is planned to compare an experimental medication designed to lower blood pressure to a placebo. Before starting the trial, a pilot study is conducted involving 7 participants. The objective of the study is to assess how systolic blood pressure changes over time untreated. Systolic blood pressures are measured at baseline and again 4 weeks later.

Drugs are often used for reducing the blood pressure of hypertensive patients (those with high blood pressure). An experiment was run to investigate the effect of Drug (A or B) and Dose Level (Low or High) on the reduction in blood pressure. The experiment was conducted separately for the 36 patients who had mild hypertension and the 24 patients who had severe hypertension as the researcher suspected that results may differ for the two groups. For this design, there are:

A clinical trial is run to look at the efficacy of a new blood pressure drug. Patients with a diagnosis of hypertension (high blood pressure) are recruited to participate in the trial and randomized to receive either the new drug or placebo. Participants take the assigned drug for 12 weeks and their blood pressure status is recorded. At the end of the trial, participants are classified as still having hypertension or not. The data are shown here: Group Number with...

A researcher has developed a new drug designed to reduce blood pressure. In an experiment, 21 subjects were assigned randomly to the treatment group, and received the new experimental drug. The other 23 subjects were assigned to the control group, and received a standard, well known treatment. After a suitable period of time, the reduction in blood pressure for each subject was recorded. A summary of these data is:                                                                                     n          x?         s                         Treatment group (new drug):               21        23.48   8.01...

In a clinical trial to study if an experimental drug can lower diastolic blood pressure, 780 participants suffering from high blood pressure were randomly assigned to one of three groups. Over a one-month period, the first group received a low dosage of the experimental drug, the second group received a high dosage of the drug, and the third group received a placebo. Neither the patients nor those analyzing the results knew what type of treatment each patient received. The diastolic...

A medical researcher wants to begin a clinical trial that involves systolic blood pressure (SBP) and cadmium (Cd) levels. However, before starting the study, the researcher wants to confirm that higher SPB is associated with lower Cd levels. Below are the SBP and Cd measurements for a sample a participants. What can the researcher conclude with an α of 0.10? SBP Cd 169 183 115 113 182 126 179 127 148 160 140 55.5 55.7 55.8 55.9 55.5 55.7 55.6...
