Two samples each of size 25 are taken from independent populations assumed to be normally distributed with equal variances. the

NeTakaya

$n_1=25, n_2=25\\ \bar{X_1}=35.5, \bar{X_2}=33\\ s_1=3, s_2=4$

Pooled Combined Variance $s_p=12.5$

Test Statistic:

$t=\frac{\left(\bar{X_1}-\bar{X_2}\right)}{s_p\sqrt{\frac{1}{n_1}+\frac{1}{n_2}}}$

$t=\frac{\left(35.5-33\right)}{12.5\sqrt{\frac{1}{25}+\frac{1}{25}}}$

$\left|t\right|=0.01414$

Degrees of freedom = $n_1+n_2-2=25+25-2=48$

$\alpha =0.05$

$t-Critical =t_{\alpha /2, n_1+n_2-2}=t_{0.025, 48}=-2.0206 \\Table value=|t|=2.0206\\|t|=2.0206$

The table value is greater than the calculated value.

Thus we accept H0.
