A new drug has been developed for a group of people and the researchers are worried that it might have an effect on pulse rate. This particular group of people has a known mean pulse rate of 82 bpm (beats per minute). A sample of 36 people taking this experimental drug is taken from the population. The mean pulse rate of the sample is 84 bpm with a standard deviation of 5 bpm. Is there evidence that the drug is changing pulse rate?

Question

Question 5 options:

1)

One sample z-test for the population mean.

2)

two sample z-test for the population means.

3)

One sample z-test for proportions.

4)

two sample z-test for proportions.

5)

one sample t-test for the population mean.

6)

None of our hypothesis tests fit.

Answer 1

The correct option is: 5) one sample t-test for the population mean.
