What is the mean age (μ) of the individuals in the population?
Understand the Problem
The question is asking for the mean age of a population, which is a statistical measure. We would typically provide a method to calculate this based on a set of ages or data points, though in this case, the specific ages are not provided.
Answer
The mean age is calculated using the formula $ \text{Mean} = \frac{\sum x_i}{n} $, depending on the provided ages.
Answer for screen readers
The answer will depend on the specific ages provided in the dataset.
Steps to Solve
- Identify the Mean Age Formula
To calculate the mean age, we need to use the formula for the mean (average), which is given by:
$$ \text{Mean} = \frac{\sum x_i}{n} $$
where $\sum x_i$ is the sum of all ages in the data set, and $n$ is the number of ages.
- Sum the Ages
You will sum all the age values provided in the data set. This results in a single total age that will then be used in the calculation of the mean.
- Count the Number of Ages
Next, you will count the total number of individual ages provided in the data set. This gives you the value of $n$.
- Calculate the Mean Age
Finally, substitute the sum of ages and the count of ages into the formula:
$$ \text{Mean} = \frac{\text{Total Age}}{\text{Number of Ages}} $$
- Final Result
The final result will be the calculated mean age of the population based on the data provided.
The answer will depend on the specific ages provided in the dataset.
More Information
To find the mean age effectively, it is essential to have all age values available. The mean is a central tendency measure and is useful in understanding the overall age distribution of a population.
Tips
- Forgetting to include all data points in the calculation.
- Incorrectly counting the number of age entries, leading to an inaccurate mean.
- Miscalculating the sum, which affects the overall average.
