**Title:** Hypothesis Testing for the Standard Deviation of Pulse Rates
**Claim:**
The standard deviation of pulse rates of adult males is more than 12 bpm. For a random sample of 128 adult males, the pulse rates have a standard deviation of 12.7 bpm. Complete parts (a) and (b) below.
---
**Part (a):** Express the original claim in symbolic form.
---
**Solution:**
To express the claim that "the standard deviation of pulse rates of adult males is more than 12 bpm" in symbolic form, we use the following notation:
- \( \sigma \) represents the standard deviation.
- The inequality symbol for "more than" is \( > \).
- Given bpm (beats per minute) is the unit.
Thus, the claim can be expressed symbolically as:
\[ \sigma > 12 \]
(Note: Ensure that the standard deviation value is written as an integer or a decimal and do not round the value).
---
**Explanation of Visual Aids:**
- The provided image shows a dropdown menu for selecting the appropriate variable (in this case, \( \sigma \)), and boxes to enter the inequality symbol and the numeric value of the standard deviation.
- The dropdown menu includes options: \( \sigma \) (standard deviation), \( p \) (proportion), and \( \mu \) (mean).
- The final symbolic form should represent that the standard deviation \( \sigma \) is greater than 12 bpm.

- The first dropdown box is for selecting the comparison operator.
- The second box is where you enter the numerical heart rate value.
#### Example:
If you want to indicate that a certain heart rate should be greater than 75 bpm, you would:
1. Select `>` from the dropdown menu.
2. Enter `75` in the text box.
Please type the numerical value considering two decimal places if necessary, but do not round off the value.

#### Data Entry for Heart Rate Analysis
When analyzing heart rate data, follow these instructions to input the correct values:
1. **Selecting the comparison operator:**
- Click on the dropdown menu to choose the appropriate comparison operator for your heart rate data. The available options are:
- `≠` (not equal to)
- `>` (greater than)
- `<` (less than)
- `=` (equal to)
2. **Entering the heart rate value:**
- After selecting the comparison operator, input the heart rate value in the provided text box.
- Ensure the value is entered as an integer or a decimal without rounding.
3. **Unit of measurement:**
- The unit for measuring heart rate is beats per minute (bpm).
Sample interface usage:

- The first dropdown box is for selecting the comparison operator.
- The second box is where you enter the numerical heart rate value.
#### Example:
If you want to indicate that a certain heart rate should be greater than 75 bpm, you would:
1. Select `>` from the dropdown menu.
2. Enter `75` in the text box.
Please type the numerical value considering two decimal places if necessary, but do not round off the value.
