Question:
a paper describes a study to determine the effects of several keyboard characteristics on typing speed. one of tthe variables considered was the front to back surface angle of the keyboard. minitab output resulting from fitting the simple linear regression model with X = surface angle (degrees) and Y = (words per minute) is given.
regression analysis: typing speed versus surface angle
the regression equation is
typing speed = 60.0+ 0.0035 surface angle
