An artic e reported that in a large study carried out in the state of New York, approximately 60% of the study subjects lived within 1 mile of a hazardous waste site. Let p denote the proportion of all New York residents who live within 1 mile of such a site, and suppose that p = 0.6. (a) Would 13 based on a random sample of only 10 residents have approximately a normal distribution? Explain why or why not. C) No, because np 10. 0 Yes, because np 10 and n(1 p) > 10. V (b) What are the mean value and standard deviation off) based on a random sample of size 410? (Round your standard deviation to four decimal places.) mean standard deviation ..(c)..W.hen.a = 0.6 0.0242 J V 410, what is P(0.55 s f; s 0.55)
