The accompanying data represent the pulse rates​ (beats per​ minute) of nine students. Treat the nine students as a population. Compute the​ z-scores for all the students. Compute the mean and standard deviation of these​ z-scores.

To solve this problem, we will follow these steps:

### Given:
- We have a dataset of pulse rates for nine students.
- We need to calculate the \( z \)-scores for each student's pulse rate.
- Then, we will compute the mean and standard deviation of the resulting \( z \)-scores.

### Formula for the \( z \)-score:

\[
z = \frac{X - \mu}{\sigma}
\]

Where:
- \( X \) is the individual student's pulse rate.
- \( \mu \) is the mean of the pulse rates.
- \( \sigma \) is the standard deviation of the pulse rates.

### Steps:
1. **Calculate the mean** \( \mu \) of the population (the nine pulse rates).
2. **Calculate the standard deviation** \( \sigma \) of the population.
3. **Calculate the \( z \)-score** for each pulse rate using the formula above.
4. **Calculate the mean and standard deviation of the \( z \)-scores**.

Please provide the pulse rates for the nine students so I can continue with the calculations.
