Coursepack, p. 589 MAT 133: 6.2 WS 3 p.2 3. A study found that 1% of Social Security recipients are too young to vote. 800 Social Security recipients are randomly selected to vote. The binomial random variable, X, represents the number who are too young to vote. (Source) a) Find the following: (Give 2 decimal places where necessary) n = P =_ H = b) Interpret u and o in the context of the situation. c) Find the probability that more than 12 out of a random group of 800 Social Security recipients are too young to vote. Give 4 decimal places. Would this be unusual? Explain. 4.
