b. Choose the clusters in the scatter plot. Select all that apply.
A.
between 8 and 11 hours​ (26 to 34​ cars)
B.
between 0 and 2 hours​ (9 to 15​ cars)
C.
between 10 and 12 hours​ (24 to 36​ cars)
D.
between 3 and 6 hours​ (5 to 13​ cars)

Answer 1

a. The outliers are (2, 39), (10, 3), and (5, 27).

b. The clusters are A (between 8 and 11 hours, 26–34 cars) and D (between 3 and 6 hours, 5–13 cars).

c. There is a gap between the low cluster and the high cluster (roughly around 6–8 hours or about 13–24 cars). A possible cause is that no days had intermediate usage — for example the lot may have been closed or access restricted during those hours, or the typical arrival pattern produces either mostly low counts early or much higher counts later (so no days fell in the middle range).
