Suppose that the distribution of typing speed in words perminute (wpm) for experienced typists using a new type of splitkeyboard can be approximated by a normal curve with mean 68 wpm andstandard deviation 17 wpm.
What is the probability that a randomly selected typist's speedis at most 68 wpm?
What is the probability that a randomly selected typist's speedis less than 68 wpm?
What is the probability that a randomly selected typist's speedis between 34 and 85 wpm? (Round your answer to four decimalplaces.)
Would you be surprised to find a typist in this population whosespeed exceeded 119 wpm? (Round your numerical value to four decimalplaces.)
It would  ---Select--- (be, not be) surprising to finda typist in this population whose speed exceeded 119 wpm becausethis probability is ________ , which is  ---Select---(very small, very large) .
Suppose that two typists are independently selected. What is theprobability that both their typing speeds exceed 102 wpm? (Roundyour answer to three decimal places.)
Suppose that special training is to be made available to theslowest 20% of the typists. What typing speeds would qualifyindividuals for this training? (Round your answer to the nearestwhole number.)
People with typing speeds of  wpmand  ---Select--- (above, below) would qualify for thetraining.
