zheka24 [161]

Answer-

In the conditional relative frequency table by column, the value of x is 0.85

Solution-

From the paint color preference table,

Liked new paint color + Disliked new paint color = 1

$\Rightarrow x+0.15 = 1$

$\Rightarrow x=1-0.15$

$\Rightarrow x=0.85$

Therefore, we have x=0.85 or 85% of adults who like the new color of the paint.
