In this assignment, you will use the method of comparing confidence intervals to test for a significant difference between the resting heart rate of males and females. You have observed that the mean rates are not exactly the same but are they significantly different?

Steps

  1. Open your Unit 5 assignment and identify the means and confidence intervals you calculated for male-at-rest and female-at-rest.
  2. Use the 95%confidence intervals to determine if the resting male heart is the same as the resting female heart.
  3. Write the null hypothesis being tested and whether you reject the null hypothesis based on the comparison of confidence intervals. Refer to the RealizeIt lesson for information on using confidence intervals to test a hypothesis.
