Listed in the table below are altitudes (in thousands of feet) and outside air temperatures (in °F) recorded by one of the authors of this text during an airplane flight. Complete parts a through d. Altitude 3 10 14 22 28 31 33 Temperature 55 37 26 −1 −30 −49 −54 a. How well does the best-fit line actually fit the points in the scatterplot? Construct a scatterplot and draw the best-fit line. Choose the correct graph below. b. Briefly discuss the strength of the correlation. Compute r and r2. Based on the value for r2, identify how much of the variation in the variable can be accounted for by the best-fit line. c. Identify any outliers on the diagram and discuss their effects on the strength of the correlation and on the best-fit line. Choose the correct answer below.
