The average typing speeds S (in words per minute) of a typing student after t weeks of lessons are shown in the table. A model for the data is given by the following: S = 100t^2 / (65 + t^2), t > 0 (a) Use a graphing utility to plot the data and graph the model. (b) Does there appear to be a limiting typing speed? Yes No What is the limit? words per minute

A publishing company wanted to test whether typing speed differs when using word processor A or word processor B. A random sample of 25 typists was selected, and the typing speeds (in words per minute) were recorded for each typist when using word processor A and then when using word processor B. (Which word processor is used first is determined for each typist by a coin flip).
