which pieces of information can be gathered from these dot plots?
choose all answers that apply:
a the top 8 olympic shot putters in the preliminary round threw farther on average than the top 8 u.s qualifiers.
b the distances of the top 8 olympic shot putters vary noticeably more than those of the top 8 u.s. qualifiers.
c none of the above

Explanation:

• For option A: By observing the dot plots, the dots for the Olympic preliminary (top 8 Olympic shot putters) are generally positioned to the right of the dots for the U.S. qualifier (top 8 U.S. qualifiers), indicating that on average, the Olympic shot putters threw farther.
• For option B: The spread of the dots (variability) for the U.S. qualifiers seems to be wider (dots from ~19 to ~21.5) compared to the Olympic preliminary (dots from ~20.5 to ~21.5), so the distances of the Olympic shot putters do not vary more. So B is incorrect.

Answer:

A. The top 8 Olympic shot putters in the preliminary round threw farther on average than the top 8 U.S qualifiers.
