I need help with this one please thank you
![### Understanding Pulse Rate Variability in Test Subjects
A certain group of test subjects had pulse rates measured with the following characteristics:
- **Mean Pulse Rate:** 73.8 beats per minute (bpm)
- **Standard Deviation:** 13.1 beats per minute (bpm)
To determine what constitutes significantly low or high pulse rates, we can apply the range rule of thumb. This rule gives us a method for identifying outliers by setting limits that mark significantly low or high values.
\[ \text{Significantly low values} \leq \text{Mean} - 2 \times \text{Standard Deviation} \]
\[ \text{Significantly high values} \geq \text{Mean} + 2 \times \text{Standard Deviation} \]
#### Example Calculation
To find if a pulse rate of 120.0 beats per minute is significantly high, follow these steps:
1. Calculate the limit for significantly low values.
\[
\text{Mean} - 2 \times \text{Standard Deviation} = 73.8 - (2 \times 13.1) = 73.8 - 26.2 = 47.6 \, \text{bpm}
\]
2. Calculate the limit for significantly high values.
\[
\text{Mean} + 2 \times \text{Standard Deviation} = 73.8 + (2 \times 13.1) = 73.8 + 26.2 = 100 \, \text{bpm}
\]
3. Compare the given value (120.0 bpm).
Since 120.0 bpm is greater than 100 bpm, it is considered significantly high.
This help text allows users to determine whether a pulse rate is significantly low or high, using a simple statistical method.
