Fitting a straight line to a set of data yields the following y I = 16 - 0.5 XiInterpret the meaning of the Y intercept, b0. Interpret the meaning of the slope, Predict the value of Y for X = 6.

Solution

a) there is no significance for this element

b) for each value of x you will have a decrease of 0.5 in Y

c)

Y = 16 - 0.5 * 6 = 13
