You will be finding probabilities using excel. Use the Excel instructions for Binomial Distribution (=BINOMDIST(x, n, p, true or false)) False is equivalent to binompdf. True is equivalent to binomedf. State which probabilities are unusual. a.) P(x <6), n = 20, p= .8 b.) P(x < 16), n = 20, p=.15 c.) P(x> 14), n = 30, p = .35 3.)
