Suppose the researchers believe that this rise in violence is due to an increase in depressive symptoms among the demographic aged 11-17. Suppose the researchers estimate that only 21% of this population suffers from depressive-like symptoms. Use a binomial distribution to solve for the following. a) What is the probability of finding no one with depressive-like symptoms in a sample of 8? (1 point) (Example answer .####) b) What is the probability that at least 2 respondents of a sample of 8 report these symptoms? (1 point) (Example answer .####) c) What is the expected number of adolescents in the sample to report the symptoms? (1 point) (Example answer #.##)
