Final Answer :
True
Explanation :
This is the definition of the arithmetic mean. Mathematically, it can be expressed as:
mean x number of observations = sum of observations
Or in symbols:
\bar{x} \cdot n = \sum_{i=1}^n x_i
where \bar{x} is the mean, n is the number of observations, and x_i are the individual observations.
mean x number of observations = sum of observations
Or in symbols:
\bar{x} \cdot n = \sum_{i=1}^n x_i
where \bar{x} is the mean, n is the number of observations, and x_i are the individual observations.
