Question

determining raw data values
the conditional relative frequency table was generated using data that compares the number of boys and girls who pack their lunch or buy lunch from the cafeteria. 35 total girls and 50 total boys were surveyed. how many students bought their lunch from the cafeteria? round to the nearest whole number.

	cafeteria	pack	total
girls	0.4	0.6	1.0
total	0.42	0.58	1.0

students

Explanation:

Step1: Calculate boys who bought lunch

Multiply boys' total (50) by cafeteria relative frequency (0.44): $50 \times 0.44 = 22$

Step2: Calculate girls who bought lunch

Multiply girls' total (35) by cafeteria relative frequency (0.4): $35 \times 0.4 = 14$

Step3: Sum the two results

Add boys' and girls' cafeteria buyers: $22 + 14 = 36$

Answer:

36
