Answer: The MEAN of the given data set is 90.
Step-by-step explanation: We are given to find the mean of the following data:
85, 97, 84, 88, 95, 100, 81
To find the mean of a data set, we need to add all the values together and divide by the number of values in the set.
In the given data, the sum of the values is given by
[tex]S=85+97+84+88+95+100+81=630,[/tex]
and the number of values is
[tex]n=7.[/tex]
Therefore, the MEAN of the data set will be
[tex]M=\dfrac{S}{n}=\dfrac{630}{7}=90.[/tex]
Thus, the required mean is 90.
