Find the positive integer value of $x$ that satisfies the equation $x^3-32x-5x^2+64=0$.

The variance $p$, $q$, $r$, and $s$ are correlated with each other with the following relationship: $\frac{s^{0.5}}{p}=\frac{q}{r^2}$

The ranges of values for $p$, $q$ and $r$ are respectively:

$-0.04\le p\le -0.03$, $-0.25\le q\le -0.09$, $1\le r\le 7$

Determine the difference between the maximum and minimum value of $s$?
