Suppose that the distribution of typing speed in words per minute (wpm) for experienced typists using a new type of split keyboard can be approximated by a normal curve with mean 76 wpm and standard deviation 19 wpm. USE SALT (a) What is the probability that a randomly selected typist's speed is at most 76 wpm? (b) What is the probability that a randomly selected typist's speed is less than 76 wpm? (c) What is the probability that a randomly selected typist's speed is between 38 and 95 wpm? (Round your answer to four decimal places.)
