help im confused and i cant figure it out can someone please explain how to do this

Answer 1

I just took the test and the correct answers are 0.25 for group 1 and 0.75 for group 2!!

Answer 2

Group1 Group2 Total
Category 1 30 90 120
Category 2 14 32 46
Total 44 122 166

Relative frequency:
Group 1 Group 2 Row Total
Category 1: 30/166 = 0.18 90/166 = 0.54 120/166 = 0.72
Category 2: 14/166 = 0.08 32/166 = 0.20 46/166 = 0.28
Column Total: 44/166 = 0.26 122/166 = 0.74 166/166 = 1.00

The relative frequency is the derived by dividing the amount per cell by the total balance, which is 166. It denotes the parts of the rows and columns against the whole table.
