For those people who like maths, I did a quick test. The counter hypothesis (null), it is equal chances to go south and north (the compass is fair with submarine as flagship as fleet 2), the probability of going 20 souths and 10 norths is less then 10% (result is significant at the 10% level - which is not super high, but it is acceptable under certain circumstances).

Quick R test result:

> binom.test(20, 30, p = 0.5)

Exact binomial test

data:  20 and 30

number of successes = 20, number of trials = 30, p-value = 0.09874

alternative hypothesis: true probability of success is not equal to 0.5

95 percent confidence interval: 0.4718800 0.8271258

sample estimates:

probability of success

0.6666667
