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

- Open your Unit 5 assignment and identify the means and confidence intervals you calculated for male-at-rest and female-at-rest.
- Use the 95% confidence intervals to determine if the resting male heart is the same as the resting female heart.
- 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.

Additional Instructions:

Your assignment should be typed into a Word or other word processing document, formatted in APA style. The assignments must include

- Running head
- A title page with
- Assignment name
- Your name
- Professor’s name
- Course

Introduction:

Comparing confidence intervals is a method used to test the significant difference between two means. In this assignment, we will use this method to compare the resting heart rates of males and females. We will determine if the observed means are significantly different from each other.

Answer:

1. The means and confidence intervals calculated for male-at-rest and female-at-rest should have been identified in the Unit 5 assignment.

2. To determine if the resting male heart is the same as the resting female heart, we need to compare the confidence intervals. If the confidence intervals overlap, then there is no significant difference between the means. However, if the intervals do not overlap, we can reject the null hypothesis that the means are equal.

3. The null hypothesis being tested is that the resting heart rates of males and females are the same. Based on the comparison of the confidence intervals, we can reject this null hypothesis if the intervals do not overlap, indicating a significant difference.
