If the formula is used to find the mean of the following sample, what is the value of n? 2, 63, 88, 10, 72, 99, 38

Rufina [12.5K]

Well since the formula for the arithmetic mean is $m= \frac{ x_{1} + x_{2} +...+ x_{n} }{n}$ $x_{1}$ thourgh $x_{n}$ will be each of the numbers (2, 63, 88, 10, 72, 99, 38) and n would be the number of numbers being added. You have 7 numbers being added making n 7 so your equation would be $m= \frac{2+63+88+10+72+99+38}{7}$
