Which of the following is the correct formula for calculating the mean?
A) $\sum \mathbf { X } + n$
B) $\sum \mathrm { X } / \mathrm { X }$
C) $\sum \mathrm { X } / n$
D) $\sum \mathrm { X } + \mathrm { X }$

The formula for calculating the mean is adding up all the values (sum) and dividing by the total number of values (n). So, the correct formula is $\sum \mathrm { X } / n$. Option A and D are not correct because they involve adding or multiplying by the number of values (n), which would result in an inflated or incorrect mean value. Option B does not make sense mathematically as dividing by a variable (X) does not cancel out the sum function.
