You are working on a clinical trial for a new drug, Straterol™, which you hope will treat patients with high blood pressure. You recruit 60 participants, take their systolic blood pressure, then give them the drug and take their blood pressure again.

If μd is the average difference in blood pressure before and after the administration of Straterol™, state the null and alternative hypotheses.

What is a type I error in terms of this experiment? What is a type II error?

At a significance level and a power of , what is the smallest detectible difference in blood pressure if the standard deviation of blood pressure is 10? Use Stata for your calculations.

Expert Solution

state the null and alternative hypotheses.

Ho : µd= 0
Ha : µd > 0

What is a type I error in terms of this experiment? What is a type II error?

Type 1 error:

Reject the null hypothesis: When you reject that average difference in blood pressure before and after the administration of Straterol is not zero but in actual it is zero.

Type 2 error:

Fail to reject the null hypothesis: When you fail to reject that average difference in blood pressure before and after the administration of Straterol is zero but in actual it is not zero and medicine worked.

for last part please provide data..could not see power and significance level data.

THANKS

A Drug Company wishes to do a clinical trial on a new antidepressant drug, “summer”. Four groups of clinically depressed participants receive: 0 mg, 5 mg, 10 mg, and 15 mg of “summer”. Depressed patients are not active so activity level as measured by the Turkey Activity Sale (TAS) was used after a two-month trial. Results were: Activity Level (TAS) 0 mg 5 mg 10 mg 15 mg 7 5 9 13 5 4 11 10 5 6 12 9 4...

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...

2. A clinical trial is conducted to evaluate the efficacy of a new drug for prevention of hypertension in patients with pre-hypertension (defined as systolic blood pressure between 120–139 mmHg or diastolic blood pressure between 80–89 mmHg). A total of 20 patients are randomized to receive the new drug or a currently available drug for treatment of high blood pressure. Participants are followed for up to 12 months, and time to progression to hypertension is measured. The experiences of participants...

A clinical trial is being conducted in order to determine the efficacy of a new drug that will be used to treat type II diabetes. The efficacy of the medication will be determined by the blood glucose readings obtained from the patients. If the researcher wants a margin of error less than or equal to 5 mg/dL and the standard deviation for blood glucose readings among type II diabetics was previous documented as 15 mg/dL, how many patients should be...
