Question

which could be a conditional relative frequency table?

Explanation:

Step1: Recall conditional relative - frequency property

In a conditional relative - frequency table, the sum of the conditional relative frequencies for each row or each column (depending on the conditioning variable) is 1.

Step2: Analyze the first table

For the first table:

• In row C: $0.25 + 0.25=0.50

eq1$

• In row D: $0.25 + 0.25 = 0.50

eq1$

• In column A: $0.25+0.25 = 0.50

eq1$

• In column B: $0.25 + 0.25=0.50

eq1$

Step3: Analyze the second table

• In row C: $0.25+0.75 = 1$
• In row D: $0.35 + 0.65=1$
• The sums of the rows are 1, which is a characteristic of a conditional relative - frequency table.

Answer:

The second table could be a conditional relative - frequency table.
