Question

Find the mean. If necessary, round to one decimal place60, 57, 86, 26, 128, 82

Answer 1

`73.2`

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

`\bar{x}=(60+57+86+26+128+82)/(6)=(439)/(6)\approx73.2`

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)
