So is it a mean of 4 errors or a mean of 32 errors?

you can always use proportions
4/1=x/8
which equals 32

A single page cannot have a mean number of typing errors, it can only have a number of typing errors. If you have 8 pages with a mean of 4 typing errors per page you have a total of 32 typing errors. The calculation of a mean implies that there is a different number of errors on each page, although some pages may have the same number.

One expects to see 32 errors; that is the probable value of the mean taken over the 8 pages.

a mean of 4 typing errors on one page.
8 pages will have a mean of 4 typing errors per page
a mean of 32 errors per 8 pages is equivalent

It is still the same mean. The mean is nothing else than the "average", if you want to see it in a certain way.
