Reseаrchers аre cоncerned аbоut the rise in gun viоlence in their community among the adolescent population. 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)[14a] (Example answer .####) b) What is the probability that at least 2 respondents of a sample of 8 report these symptoms? (1 point)[14b] (Example answer .####) c) What is the expected number of adolescents in the sample to report the symptoms? (1 point)[14c] (Example answer #.##)
