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.
