The grand mean of the process mean of the samples taken by the workers is 12.072

The mean is the numerical average of a set of two or more numbers. The equation for calculating the mean is by adding up the numbers in a set and dividing by the entire amount of numbers within the set. A mean makes a difference in you evaluate a set of numbers by telling you the average, making a difference to contextualize each information point. Here the grand mean will be the average mean of the total means obtained from the samples.

SIince we are given the means obtained by the workers which are 12.08, 12.07, 12.07, 12.07, and 12.07.

So considering T to be the grand mean and number of observations are 5,

So,

T =12.08 +12.07+ 12.07 +12.07+ 12.07/5

= 12.072
