Use the data given in the three scenarios below to produce scatter plots, determine the type of model demonstrated in each example and then answer the questions based on the graph you created. Scenario 1 Rescue 911 In a rural community, fire and paramedic crews must service a large region. They often cover 2 or 3 towns several kilometres apart. These crews travel, on average, 70 km/h to their destination. The Chief of Station 42 wants to determine the time required to reach the patient's home (response time) for his region. The station is located next to the local hospital. The Chief knows the distances to each community that he services, including Deerborn, the furthest community, at 55 km away. Using the data below, create a scatter plot showing the relationship between distance to patient and response time. Distance to Patient (km) Response Time (minutes) 10 8.6 15 12.9 40 34.3 50 42.9 55 47.1

Suppose a researcher collects data on the bacterial contamination, measured in colony-forming unit per milliliter, for both upstream and downstream sections of 35 rivers. The data is plotted with upstream bacterial contamination on the horizontal axis and downstream bacterial contamination on the vertical axis. The Scioto River is an outlier in the ?y‑direction. What must be true about this river? The upstream bacterial contamination for this river is much higher or lower than the rest of the rivers in the data set. The downstream bacterial contamination for this river is much higher or lower than other rivers in the data set that have similar upstream bacterial contamination. This river is an influential observation. The downstream bacterial contamination for this river is much higher or much lower than the rest of the rivers in the data set. The absolute value of the residual of this river is large.

1. Graph= A line and several approximate points are in a coordinate plane. The horizontal axis is labeled "t". The vertical axis is labeled "P". The line enters the viewing window in the second quadrant and goes up and right. It crosses the P-axis at approximately P = 16.0. The first point is located at (6, 17.2), and is on the line. The second point is located at (7, 17.5), and is nearly on the line. The third point is located at (8, 17.5), and is on the line. The fourth point is located at (9, 17.8), and is on the line. The fifth point is located at (10, 17.8), and is nearly on the line. The sixth point is located at (11, 18.2), and is nearly on the line. The seventh point is located at (12, 18.4), and is on the line. The eighth point is located at (13, 18.3), and is slightly below the line.
