### Your Input

**Find the arithmetic mean of $$$1$$$, $$$4$$$, $$$5$$$, $$$3$$$, $$$2$$$.**

### Solution

The arithmetic mean of data is given by the formula $$$\mu = \bar{x} = \frac{\sum_{i=1}^{n} x_{i}}{n}$$$, where $$$n$$$ is the number of values and $$$x_i, i=\overline{1..n}$$$ are the values themselves.

Since we have $$$5$$$ points, $$$n = 5$$$.

The sum of the values is $$$1 + 4 + 5 + 3 + 2 = 15$$$.

Therefore, the arithmetic mean is $$$\mu = \bar{x} = \frac{15}{5} = 3$$$.

### Answer

**The arithmetic mean is $$$\mu = 3$$$A.**
