Please answer step by step solution

AP3.33. Anuclear power plant releases water into a nearby lake every afternoon at 4:51 P.M. Environmental research- ers are concerned that fish are being driven away from the area around the plant. They believe that the temperature of the water discharged may be a factor. The seatterplot below shows the temperature of the water (°C) released by the plant and the measured distance (in meters) from the outflow pipe of the plant to the nearest fish found in the water on eight randomly chosen afternoons. 160 - 140 120 100 15 20 25 30 35 Temperature Computer output from a least-squares regression analys on these data is shown below.
