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.© SolutionLibrary Inc. solutionlibary.com 9836dcf9d7 https://solutionlibrary.com/statistics/descriptive-statistics/statistics-help-random-sample-31p
What you do is the following:
The expected mean - the actual mean / standard deviation
Therefore the T- statistic would be: 74.5-76/8.7
This is you T statistic.
Now you have to compare this test statistic to the critical value.
Now because the alternative ...
