Question

a medical researcher wants to measure the effects of a new drug on cholesterol levels using a hypothesis test. The target is a 30-point decrease in cholesterol levels after a treatment cycle. The researcher takes a random sample of patients and meAsures their cholesterol levels before and after a treatment cycle of the drug. Which type of hypothesis test should they use?
A) test for a difference in two population mean B)test for a difference in two population proportions C) test for one population mean D)test for one population proportion a medical researcher wants to measure the effects of a new drug on cholesterol levels using a hypothesis test.

Explanation / Answer

The researcher using the same sample of data for pre and post-treatment. A hypothesis test is to measure the difference between means of pre and post-treatment.

Whenever one sample of data is paired with another sample for observations, the paired difference test will be used to test the hypothesis.

Answer A) Test the difference in two population mean.

B) Data is not representing proportions. It representing the level of cholesterol.

C) The test is before and after treatment. we can't apply this technic.

D)Data is not representing proportion.
