### Problem Statement
Evaluate the following formula for:
- \( \bar{x}_1 = 27.9785 \)
- \( \bar{x}_2 = 25.5651 \)
- \( \mu_1 - \mu_2 = 0 \)
- \( s_p = 43.29 \)
- \( n_1 = 41 \)
- \( n_2 = 43 \)
### Formula
\[
t = \frac{ \left( \bar{x}_1 - \bar{x}_2 \right) - \left( \mu_1 - \mu_2 \right) }{ \sqrt{ \frac{ s_p^2 }{ n_1 } + \frac{ s_p^2 }{ n_2 } } }
\]
### Calculation Box
\[
t = \boxed{ \ } \quad (\text{Round to two decimal places as needed.})
\]
