Question 3 of 5 Attempt 3 Spell-checking software catches nonword errors that result in a string of letters that is not a word, as when "the" is typed as "teh." When undergraduates are asked to type a 250-word essay, without spell-checking, the number X of nonword errors has the provided distribution. Value of X 0 1 2 3 4 Probability 0.1 0.2 0.3 0.3 0.1 (a) Is the random variable X discrete or continuous? Why? Discrete, because it has a finite number of possible values: 0, 1, 2, 3, 4. Discrete, because we do not know the number of errors in advance. O Continuous, because all the probabilities are between 0 and 1. O Continuous, because there can be all sort of errors. (b) Which statements are equivalent to the event "at least one nonword error" in terms of X? Select all that apply. Ox0 Question Source: Moore, The Basic Practice Of Statistics, 8e | Publisher: W.H.
