​Which statement is supported by the data in the dot plot?
A
More than half of the birds have wing lengths of less than 505050 millimeters.
B
There are more birds that have a wing length of 545454 millimeters than birds that have a wing length of 464646 millimeters.
C
Fewer than half of the birds have wing lengths greater than 484848 millimeters.
D
There are more birds that have a wing length of 525252 millimeters than birds that have a wing length of 515151 millimeters.

Answer 1

I can’t view the dot plot image you mentioned. Please either upload the image again or list how many dots are at each wing-length value (for example: 46 mm: 1, 48 mm: 2, 50 mm: 3, …).

How to check each choice once you have the counts:
- A: Count all dots at values < 50. If that count is greater than 5 (more than half of 10), A is true.
- B: Compare the count at 54 mm to the count at 46 mm; B is true if the 54-mm count is larger.
- C: Count all dots at values > 48. If that count is less than 5 (fewer than half), C is true.
- D: Compare the count at 52 mm to the count at 51 mm; D is true if the 52-mm count is larger.

Send the counts or the image and I’ll pick the correct choice.
