# Statistics help: Random Sample

A random sample of 15 women yielded a mean pulse rate of 74.5 beats/minute with a standard deviation of 9.6. A random sample of 12 men yielded a mean pulse rate of 76.0 beats/minute with a standard deviation of 8.7. Test the claim that pulse rates for men and women are the same. Use V = 0.01.

Use the traditional methods for testing hypotheses and show the results of all steps in the process.

#### Solution Preview

The first step is that you have to set up your hypothesis:

Null Hypothesis:

Ho: The pulse rate for men and woman are the same at 74.5

Alternative Hypothesis

Ha: The pulse rate for men and woman are NOT the same.

Now you have to set up equation to calculate the test statistics - ...

#### Solution Summary

The solution addresses a random sample of 15 women yielded a mean pulse rate of 74.5 beats/minute with a standard deviation of 9.6. A random sample of 12 men yielded a mean pulse rate of 76.0 beats/minute with a standard deviation of 8.7. Test the claim that pulse rates for men and women are the same. Use V = 0.01 and uses the traditional methods for testing hypotheses and show the results of all steps in the process.
