1. The problem asks to find the missing value $x$ in the conditional relative frequency table by column. 2. The table shows paint color preference for Children and Adults with totals by row and column. The totals for each column must sum to 1.0. 3. For the Adults column, the sum of liked and disliked frequencies must be 1.0: $$x + 0.15 = 1.0$$ 4. Solve for $x$: $$x = 1.0 - 0.15$$ $$x = 0.85$$ 5. Therefore, the missing value $x$ that completes the conditional relative frequency table by column is $0.85$. This means 85% of adults liked the new paint color.
