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 10 word errors. (a) If X is the number of word errors missed, what is the distribution of X ? Select an answer choice. X is binomial with n = 10 and p = 0.7 X is binomial with n = 10 and p = 0.3 X is approximately Normal with μ = 3 and σ = 1.45 X is Normal with μ = 7 and σ = 1.45 If Y is the number of word errors caught, what is the distribution of Y ? Select an answer choice. Y is Normal with μ = 7 and σ = 1.45 Y is approximately Normal with μ = 3 and σ = 1.45 Y is binomial with n = 10 and p = 0.3 Y is binomial with n = 10 and p = 0.7 (b) What is the mean number of errors caught? (Enter your answer as a whole number.) mean of errors caught = What is the mean number of errors missed? (Enter your answer as a whole number.) mean of errors missed = (c) What is the standard deviation of the number of errors caught? (Enter your answer rounded to four decimal places.) standard deviation of the number of errors caught = What is the standard deviation of the number of errors missed? (Enter your answer rounded to four decimal places.) standard deviation of the number of errors missed =

Someone answer asap for ! max recorded the heights of 500 male humans. he found that the heights were normally distributed around a mean of 177 centimeters. which statements about max’s data must be true? a. the median of max’s data is 250 b. more than half of the data points max recorded were 177 centimeters. c. a data point chosen at random is as likely to be above the mean as it is to be below the mean. d. every height within three standard deviations of the mean is equally likely to be chosen if a data point is selected at random.
