Data Table Departure Delay (minutes) 104 Arrival Delay (minutes) 92 83 30 Departure Delay (minutes) Full data set I; Arrival Delay (minutes) 15 12 11 51 0 15 19 12 7 - 4 1 96 14 (a) Do you expect the number of minutes that the ight is delayed departing to be associated with the arrival delay? 0 A. Yes, because the arrival delay affects the departure delay. 0 B. No, because the arrival delay does not affect the departure delay. 0 c. No, because the departure delay does not affect the an'ival delay. 0 D. Yes, because the departure delay affects the arrival delay. 0 E. No, because the pilot can choose to make up time if there is a departure delay. (b) Make a scatterplot of the arrival delay (in minutes) on the departure delay (also in minutes). Summarize the association present in the scatterplot, if any. Make a scatterplot of the arrival delay on the departure delay. Choose the correct graph below. OA- OB.

The data in the accompanying table summarize the status of a sample of 40 flights. Complete parts a through e.Summarize the association present in the scatterplot, if any. Select the correct choice below and, if necessary, ll in the answer box to complete your choice. O A- There is a strong positive curved trend, with a pronounced outlier at . O 3- There is a strong negative curved trend, with a pronounced outlier at (Type an ordered pair.) (Type an ordered pair.) 0 C. There is a weak positive linear trend, with a pronounced outlier at . O D- There is a weak positive curved trend, with a pronounced outlier at (Type an ordered pair.) (Type an ordered pair.) 0 5- There is a strong positive linear trend, with a pronounced outlier at . O F- There is a strong positive linear trend, With "0 outliers 0" surprises. (Type an ordered pair.) (c) Find the correlation between arrival delay and departure delay. corr(x, y) = D (Round to three decimal places as needed.) (d) How is the correlation affected by the evident outlier, a ight with very long delays? O A. The outlier increases the correlation. O B. The outlier decreases the correlation. O c. The outlier does not affect the correlation. (e) How would the correlation change if delays were measured in hours rather than minutes? 0 A. The new correlation would be equal to the original correlation divided by 360. O B. The new correlation would be equal to the original correlation times 360. O C. The new correlation would be equal to the original correlation divided by 60. O D. The new correlation would be equal to the original correlation times 60. O E. The correlation would not change
