Typing Speed and Word Processing A researcher desires to know whether the typing speed of a secretary (in words per minute) is related to the time (in hours) that it takes the secretary to learn to use a new word processing program. The data are shown. Speed x  48 74 52  79  83 56  85 63  88  74  90  92 Time y      7   4   8  3.5   2   6  2.3  5  2.1 4.5 1.9 1.5 If there is a significant relationship, predict the time it will take the average secretary who has a typing speed of 72 words per minute to learn the word processing program. (This information will be used for Exercises 9 and 11.)
