The following regression model has been computed based on a sample of 70 observations of part-time workers. The regression equation that relates the number of hours worked (x) and the individual weekly income (y in 100 AED) is ŷ equals 35.4 plus 5.2 x What does the intercept mean in this context? Part-time workers who did not work at all are expected to earn a weekly income of 3540 AED. The intercept has no meaning. For every additional hour of work, the weekly income is expected to increase by  520 AED. Part-time workers who did not work at all are expected to earn a weekly income of 35.4 AED.
