Solution

First shot.

The evaluation is one tailed.

There are 10 plus signs. Under p = 0.5 n=12 the probability is 0.0161

0.0161> 0.1 we fail to reject null hypothesis and you cannot conclude that human interaction increases interacting between monkeys

Type I error

Second screen shot

The new probability becomes 0.0018*2 = 0.0036. The new probability is still < than alpha the professor can still reject the null hypothesis and she can conclude the new alternative hypothesis.
