2. Suppose that the distribution of net typing rate in words per minute (wpm) for experienced typists is normal with mean 60 wpm and standard deviation 15 wpm. Find the probability that the randomly selected typist's net rate is (a) (4 points) at most 60 wpm. Answer: (b) (4 points) over 100 wpm. Answer: (c) (4 points) between 60 and 100 wpm. Answer: (d) (4 points) Suppose that special training is to be made available to the slowest 10% of the typists. What typing speeds would qualify individuals for this training? Answer:
