The scatterplot shows the ticket cost 7 ($) and distance D (miles) for a variety of airplane flights. The scatterplot shows the ticket cost 7 ($) and distance D (miles) for a variety of airplane flights. 120 1200 1000 800 800 The equation of the trendline is: Ticket Cost (Dollars) Ticket Cost (Dollars) 600 The equation of the trendline is: 400 T = 458 + 0.15D 400 T = 458 + 0.15D 200 200 0 0 1000 2000 3000 4000 5000 1000 2000 3000 4000 5000 Flight Distance (Miles) Flight Distance (Miles) 1. Based on what you observe in the scatterplot, are the variables "flight distance" and "travel cost" positively correlated, negatively correlated, or uncorrelated? Write a complete sentence to 4. Use the equation of the trendline to predict the cost of a ticket for a flight that is 892 miles long. Round explain your choice. In your sentence, use directional words like increase and decrease. to the nearest whole dollar. Show your calculations. (1 pt) (1.5 pt) 5. Did you interpolate or extrapolate in #4? (0.5 pt) 2. If there is a correlation, state whether you think it is probably due to coincidence, common cause, or cause-and-effect. Write a complete sentence to explain your choice. (If there is no correlation, write "not applicable".) (1.5 pt) 6. One of the flights in the scatterplot was 892 miles long and the ticket was $611. Was this real-life ticket price higher or lower than the one you predicted? By how many dollars? Show your calculations. (1 pt ) 3. Identify the initial value and growth rate of the trendline (including units) and write a complete sentence that interprets the meaning of each. If the interpretation is not practical, say so. a. Initial value: (1.5 pt) b. Growth rate (1.5 pt) 7. Use the equation of the trendline to estimate the length of a flight that has a ticket cost of $1000. Round to the nearest whole mile.
