Question

last july, 160 babies were born in a hospital in maine; \\(\frac{3}{5}\\) of the babies were girls. seventy babies weighed 8 pounds or more. fifty boys weighed 8 pounds or more. if that data was represented in a two - way table, which of the following could correctly describe the category variables?\
\\(\circ\\) column: boys, less than 8 pounds; row: girls, 8 pounds or more\
\\(\circ\\) column: boys, 8 pounds or more; row: girls, less than 8 pounds\
\\(\circ\\) column: less than 8 pounds, 8 pounds or more; row: boys, girls

Explanation:

Step1: Analyze the data categories

The data involves two main categorical variables: gender (boys, girls) and weight category (less than 8 pounds, 8 pounds or more). A two - way table should have one variable for rows and one for columns.

Step2: Evaluate each option

• Option 1: The column and row categories are a mix of gender and weight, which is not a proper two - way table structure (should have one type of variable per axis).
• Option 2: Similar to option 1, the column and row categories are a mix of gender and weight, not a proper structure.
• Option 3: The column variable is the weight category (less than 8 pounds, 8 pounds or more) and the row variable is the gender (boys, girls), which is a proper two - way table structure as it separates the two categorical variables (gender and weight) into row and column axes.

Answer:

C. Column: Less Than 8 Pounds, 8 Pounds or More; Row: Boys, Girls
