Which statement is best supported by the data?

  2. B. Sales rose on every day shown.
  3. C. The coolest day had the highest sales.
  4. D. Temperature alone explains each day's sales.

B. Sales rose on every day shown.
Thursday's sales fell from Wednesday's.
C. The coolest day had the highest sales.
Monday, the coolest, had the lowest sales.
D. Temperature alone explains each day's sales.
Tuesday and Thursday had the same temperature and very different sales.
