Answer
$lower~critical~value\lt r\lt upper~critical~value$: null hypothesis is not rejected.
There is not enough evidence to conclude that the winning division does not occur randomly.
Work Step by Step
$H_0:~The~sequence~is~random$ versus $H_1:~The~sequence~is~not~random$
$n=25$, $n_W=14$, $n_E=11$ and $r=13$
Small sample case:
$lower~critical~value=8$
$upper~critical~value=19$
(According to table X, for $n_1=14$, $n_2=11$)
Test statistic: $r=13$
Since $lower~critical~value\lt r\lt upper~critical~value$, we do not reject the null hypothesis.
