The following summary statistics were obtained from a data set on the effects of bike lanes on driver and bicyclist behaviour. In the following x = available travel space for cars (in feet), which is the distance between a cyclist and the roadway centre line, and y = separation distance between a bike and a passing car (determined by photography).

n = 10, xi = 154.2, yi = 80, x2i = 2452.18, yi2 = 675.16, xiyi = 1282.74

[a] Find the estimated line of regression of Y on X.
