Solution:-
4) Statistical power is the probability of detecting an effect when it exists.
5)The null hypothesis would not be rejected.
Since t-value(1.93) is less than tcritical(1.96), hence null hypothesis could not be rejected.
6) The mean number of crimes for juveniles in the poverty group(M = 2.45) is significantly higher than the mean number of crimes for juviniles in the non-poverty group(M = 0.95), t(40) = 3.41, p < 0.01.
