Question

(100 POINTS- ANSWERED!!!!! -FOR POINTS!!!!) High school students surveyed about which math and science topics they preferred. They were asked to choose algebra or geometry, and biology or chemistry. The results are shown in the frequency table below.

Use this table to create a relative frequency table by row.

Answer 1

• Relative Frequency = [Frequency of the event occuring/ Total frequency] x 100%

#Biology

• Algebra = 67/92 = 0.728 ≈ 0.73 = 73%
• Geometry = 25/92 = 0.27= 27%
• Total = 92/92 = 1 = 100%

#Chemistry

• Algebra = 46/66 = 0.696 ≈ 0.70 = 70%
• Geometry = 20/66 = 0.30 = 30%
• Total = 66/66 = 1 = 100%

#Total

• Algebra = 113/158 = 0.715 = 72%
• Geometry= 45/158 = 0.284 = 28%
• Total = 158/158 = 1 = 100%
