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.

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.
