A very skilled court stenographer makes one typographical error (typo) per hour on average. (a) What probability distribution is most appropriate for calculating the probability of a given number of typos this stenographer makes in an hour? O Poisson O binomial O negative binomial O geometric (b) What are the mean and the standard deviation of the number of typos this stenographer makes? (Enter your answers as whole numbers.) mean standard deviation 1 1 (c) Would it be considered unusual if this stenographer made 5 typos in a given hour? Making 5 typos in a given hour is more than two standard deviations above the mean, so it would be unusual. (d) Calculate the probability that this stenographer makes at most 5 typos in a given hour.
