the mean.

​(Type an integer or decimal rounded to two decimal places as​ needed.)

To interpret this problem, we need to determine how many standard deviations an age of 2020 is from the mean.

The general formula to calculate the number of standard deviations a value is from the mean is:

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

Where:
- \( z \) is the number of standard deviations from the mean,
- \( x \) is the value (in this case, 2020),
- \( \mu \) is the mean,
- \( \sigma \) is the standard deviation.

However, this problem doesn't provide the values for the mean (\( \mu \)) or the standard deviation (\( \sigma \)). To complete the problem, you would need these values. If you provide the mean and the standard deviation, I can calculate the exact number of standard deviations the value 2020 is from the mean.

Do you have the mean and the standard deviation values? Would you like to proceed with an example or provide further details?

Here are 5 related questions to consider:
1. What is the formula to calculate the z-score?
2. How is the mean calculated in a data set?
3. What role does standard deviation play in statistics?
4. How can z-scores help interpret data in a normal distribution?
5. Why is it important to round decimal values appropriately in statistics?

**Tip:** When calculating z-scores, always ensure that the data follows a normal distribution for accurate interpretation.

An age of 2020 is above or below the mean by how many standard deviations?
