5
of the babies were girls. Seventy babies weighed 8 pounds or more. Fifty boys weighed 8 pounds or more. Which of these tables best represents the data?

To determine which table best represents the data, we need to analyze the given information and match it with the options provided. Let's break it down:
1. Last July, 160 babies were born in a hospital in Maine.
- This means that the "Total" column for the "boys" and "girls" entries should add up to 160.
2. 35% of the babies were girls.
- This implies that the "girls" entry in the "Total" column should be 35% of 160, or 0.35 * 160 = 56.
3. Seventy babies weighed 8 pounds or more.
- This indicates that the "greater-than-or-equal-to 8 pounds" entry in the "Total" column should be 70.
4. Fifty boys weighed 8 pounds or more.
- This means that the "boys" entry in the "greater-than-or-equal-to 8 pounds" column should be 50.
Analyzing the given options:
- Option A: The entries for the "girls" and "Total" columns do not match the information provided.
- Option B: The entries for the "girls" and "Total" columns do not match the information provided.
- Option C: The entries for the "greater-than-or-equal-to 8 pounds" column match the given information, but the entries for the "Total" and "girls" columns do not match.
Therefore, the correct answer is:
A 4-column table with 3 rows. Column 1 has entries boys, girls, total. Column 2 is labeled less than 8 pounds with entries blank, blank, blank. Column 3 is labeled greater-than-or-equal-to 8 pounds with entries 50, blank, 70. Column 4 is labeled Total with entries blank, 96, 160.
