question 16

Multiple Choice

In a study of reaction times, the time to respond to a visual stimulus (x) and the time to respond to an auditory stimulus (y) were recorded for each of 6 subjects. Times were measured in thousandths of A second. The results are presented in the following table.
The following MINITAB output describes the fit of a linear model to these data. Assume that the assumptions Of the linear model are satisfied.
The regression equation is Auditory $= 169.803813 + 0.4671$ Visual
