A typist makes an average of 4 typo errors per page that she types. If the number of errors per each typed page can be modeled according to the Poisson distribution, what is the probability that she will make more than 3 typo errors in the next page?

An educational psychologist hypothesizes that individuals not using a word-processing grammar-checker will make more grammatical errors in a hand-written draft. At a local university, the average number of errors per page is 7 for a hand-written writing test. To investigate, a sample of university students was prohibited from using a grammar-checker for a semester. What can the psychologist conclude with α = 0.01? The data are below. id error 8 1 3 4 5 7 11 21 19 15 45...
