A data set has n = 30, P30 i=1 xi = 67, P30 i=1 yi = 1322, P30 i=1 x2 i = 582, P30 i=1 y2 i = 60600, P30 i=1 xiyi = 3840. Calculate ˆ 0, ˆ 1 and ˆ2.

An observer(o) spots a plane(p) taking off from a local airport and flying at a 29 degree angle horizontal to her line of sight and located directly above a tower(t). the observer also notices a bird circling directly above her. if the distance from the plane(p) to the tower(t) is 6,000ft., how far is the bird(b) from the plane(p).
