# 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.

This is you T statistic.

Now you have to compare this test statistic to the critical value.

Now because the alternative ...
