Answer: b) 15.7

<u>Step-by-step explanation:</u>

Look at the z-table (below) to find 0.2500

Notice that the value is not on the table but is between 0.2486 and 0.2517 which are located on the z-table at 0.67 and 0.68

The given value is closer to 0.2486 so use 0.67 as the z-score.

Now, let's find the x-value using the formula: $z=\dfrac{x-\mu}{\sigma}$

$-0.67=\dfrac{x-20}{6.4}\\\\\\\text{Multiply both sides by 6.4:}\\-4.288=x-20\\\\\\\text{Add 20 to both sides:}\\\large\boxed{15.712} = x$
