Answer 2

A two-way frequency table is used to represent data in rows and columns.

To complete the column two-way relative frequency table, we simply divide the cell element by the total value on that column.

So, we have:

$8th = \frac{55}{145} = 38\%$ --- 0 - 300

$7th = \frac{61}{155} = 39\%$ --- 300+

For the total cells, we simply add up the cells above them:

So, we have:

$7th = 61\% + 39\%= 100\%$ --- total

$8th = 38\% + 62\% = 100\%$ --- total

Hence, the complete column two-way relative frequency table is:

                   7th         8th       Total

0 - 300        61%      38%       50%

300+           39%      62%       50%

Total           100%     100%       100%
