between 3 and 6 hours​ (5 to 13​ cars)
Your answer is correct.B.
between 8 and 11 hours​ (26 to 34​ cars)
Your answer is correct.C.
between 10 and 12 hours​ (24 to 36​ cars)
D.
between 0 and 2 hours​ (9 to 15​ cars)
Part 3

A.
There is a gap between 6 and 10 hours​ (3 to 12​ cars). The car owners may be leaving work and therefore not parking their cars during that time.
B.
There is a gap between 6 and 8 hours​ (15 to 24​ cars). The car owners may be traveling and therefore not parking their cars during that time.

D.
There is a gap between 2 and 5 hours​ (27 to 39​ cars). The car owners may have gone to breakfast and then gone home.

Answer 1

a. Outliers: (2, 39), (10, 3), (5, 27)

b. Clusters: A (between 3 and 6 hours, 5–13 cars) and B (between 8 and 11 hours, 26–34 cars)

c. Gaps: A and B.
- A: gap roughly 6–10 hours for low counts (3–12 cars) — few or no points in that region.
- B: gap roughly 6–8 hours for mid counts (15–24 cars) — separates the low-car cluster from the high-car cluster.
Possible cause: a change in parking demand/usage (e.g., a period when fewer people park — commuting patterns or trips away from the lot).
