The mean of data is given by the ratio of the sum of all the values to the total number of values. It gives the average value of the set of values.
[tex]\bar{x}=\frac{1}{n}}\left(\sum _{i=1}^{n}{x_{i}}\right)[/tex]
Here, the manager wants to get an estimate of how much time it takes by each employee to complete a task. The mean will be the sum of time taken by each person to complete a task divided by the number of employees.
