NBC News reported on May 2, 2013, that 1 in 20 children in the United States have a food allergy of some sort. Consider selecting a random sample of 15 children and let X be the number in the sample who have a food allergy. Then x - Bin(15, 0.05). (Round your probabilities to three decimal places.) (a) Determine both P(X s 2) and P(X < 2). P(X S 2) = P(X < 2) = (b) Determine P(X 2 3). P(X 2 3) = (c) Determine P(1 sXs 2). P(1 sxS 2) = (d) What are E(X) and o,? (Round your answers to two decimal places.) E(X) = (e) In a sample of 70 children, what is the probability that none has food allergy? You may need to use the appropriate table in the Appendix of Tables to answer this question.

NBC News reported on May 2, 2013, that 1 in 20 children in the United States have a food allergy of some sort. Consider selecting a random sample of 15 children and let X be the number in the sample who have a food allergy. Then X ~ Bin(15, 0.05). (Round your probabilities to three decimal places.) (a) Determine both P(X < 2) and P(X < 2). P(X < 2) = P(X < 2) = (b) Determine P(X > 3). P(X > 3) (c) Determine P(1 < X < 2). P(1 < X < 2) = (d) What are E(X) and o,? (Round your answers to two decimal places.) E(X) = Ox = (e) In a sample of 70 children, what is the probability that none has a food allergy? You may need to use the appropriate table in the Appendix of Tables to answer this question.
