We prove two general formulas for a two-parameter family of hypergeometric
$\3F2(z)$ functions over a finite field $\F_q$, where $q$ is a power of an odd
prime. Each formula evaluates a $\3F2$ in terms of a $\2F1$ over $\F_{q^2}$. As
applications, we evaluate infinite one-parameter families of $\3F2(\frac{1}{4})$
and $\3F2(-1)$, thereby extending results of J. Greene--D. Stanton and K. Ono,
who gave evaluations in special cases.
