Question

algebra i b-cr
which could be a conditional relative frequency table?

first table
a b total
c 0.25 0.25 0.50
d 0.25 0.25 0.50
total 0.50 0.50 1.0

second table
a b total
c 0.25 0.75 1.0
d 0.35 0.65 1.0
total 0.30 0.70 1.0

third table
a b total
c 0.75 0.25 0.50

mark this and return save and exit

Explanation:

Step1: Recall conditional relative frequency rules

A conditional relative frequency table uses row or column totals as the denominator for calculations. For row conditional relative frequencies, each row's values sum to 1.0; for column conditional, each column's values sum to 1.0.

Step2: Analyze first table

Row totals are 0.50, not 1.0, column totals are 0.50, not 1.0. This is a joint frequency table, not conditional.

Step3: Analyze second table

Each row's values sum to 1.0 (0.25+0.75=1.0; 0.35+0.65=1.0). This matches row conditional relative frequency rules, where row totals are the base for calculations.

Step4: Analyze third table

Row totals are 0.50, not 1.0, so it is not a conditional relative frequency table.

Answer:

The second table:

	A	B	Total
D	0.35	0.65	1.0
Total	0.30	0.70	1.0
