3) Do people drive more slowly on tree-lined street? In the following table x is a random variable representing the number of tree per mile of road on randomly selected streets with a 25 mph speed limit in a major city while y represents the average speed of cars in mph sampled over a one-hour period at the same time of day X 47 5 25 12 30 y 25 50 44 45 35 a) Draw a Scatter Plot Diagram of the data. Remember to label the axes appropriately and choose a consistent scale. b) Based on the Scatter Plot Diagram, would you estimate the correlation coefficient to be positive, close to zero, or negative: 3) Do people drive more slowly on tree-lined street?
