Question
Typing 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 12 word errors.
Typing 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 errons 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 12 word errors.Explanation / Answer
This will be a binomial distribution with parameters:
n = 12, p = 0.70
So,
P(3 or more)
= 1 - P(X < 3)
= 1 - binomdist(2, 12, 0.70, TRUE) [Excel Formula]
= 0.9998
