Typographic errors in a text are either nonword errors (as when "the" is typed as "teh") or word errors that result in a real but incorrect word. spell-checking software will catch nonword errors but not word errors. human proofreaders catch 70% of word errors. you ask a fellow student to proofread an essay in which you have deliberately made 10 word errors. what is the smallest number of misses m with p(x ≥ m) no larger than 0.05? you might consider m or more misses as evidence that a proofreader actually catches fewer than 70% of word errors.
