Independent random samples selected from two normal populations produced the
following sample means and standard deviations. $\begin{array}{ll}\text { Sample 1 } & \text { Sample 2 } \\n_{1}=14 & n_{2}=11 \\\bar{x}_{1}=7.1 & \bar{x}_{2}=8.4 \\s_{1}=2.3 & s_{2}=2.9\end{array}$

Conduct the test $H _ { 0 } : \left( \mu _ { 1 } - \mu _ { 2 } \right) = 0$ against. $H _ { a } : \left( \mu _ { 1 } - \mu _ { 2 } \right) \neq 0$ , Use $\alpha = .05$ .
