Hello everyone, I would like some help with this exercise:
To determine whether the conduct at school is different from the conduct at home, were studied 10 children treated for psychiatric illness. The behavior is measured on a scale from 1 to 100. 7 differences were observed to be positive and 2 negative. Applying the binomial distribution:
A) compute the probability of a negative or no difference assuming p = 0.5
B) assuming alpha = 0.05, a tail, we refuse or not the null hypothesis in favor of the hypothesis that the behavior at school is different, with a score greater than at home?
