Transcribed Image Text:### Pulse Rates in Adult Males and Females
**Objective:**
The table below lists pulse rates (beats per minute) from samples of adult males and females. The goal is to determine if there is a noticeable difference between the two groups by finding the coefficient of variation for each sample and then comparing these variations.
#### Pulse Rates (beats per minute)
- **Male:** 90, 68, 84, 90, 70, 61, 82, 56, 85, 84, 71, 80, 82, 100, 50, 86
- **Female:** 88, 84, 81, 71, 72, 84, 89, 87, 88, 79, 80, 76, 78, 76, 78
#### Task:
Find the coefficient of variation for each of the two samples, then compare the variations.
#### Explanation:
- **Coefficient of Variation (CV):**
- It is a statistical measure of the relative variability of the data.
- It is calculated as the ratio of the standard deviation to the mean (average) and is expressed as a percentage.
The coefficient of variation for the male pulse rates is ___ %
(Type in integer or decimal rounded to one decimal place as needed)
