[tex]73.2[/tex]

1) We need to add them up over the number of data points. By doing this we can write out the following:

[tex]\bar{x}=\frac{60+57+86+26+128+82}{6}=\frac{439}{6}\approx73.2[/tex]

Note that we don't need to write the data points in order to find the mean.

Thus, the answer is 73.2 (to the nearest tenth)
