Question

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.)
