Suppose that 90% of all registered voters in a certain state favor banning the release of information from exit polls in presidential elections until after the polls in that state close. A random sample of 25 registered voters is to be selected. Let x be the number of registered voters in this random sample who favor the ban. (a) What is the probability that more than 20 voters favor the ban?

(b) What is the probability that at least 20 favor the ban?

(c) What are the mean value and standard deviation of the number of voters who favor the ban?

answer:   segregation violated the equal protection clause of the 14th amendment, which holds that no state can “deny to any person within its jurisdiction the equal protection of the laws.”

details/explanation:

brown v. board of education of topeka, decided by the us supreme court in 1954, ruled that all americans are entitled to the same civil liberties and protections in regard to access to education. until that decision, it was legal to segregate schools according to race, so that black students could not attend the same schools as white students.   an older supreme court decision, plessy v. ferguson (1896), had said that separate, segregated public facilities were acceptable as long as the facilities offered were equal in quality.   in the case of brown v. board of education, that standard was challenged and defeated.   segregation was shown to create inequality, and the supreme court unanimously ruled segregation to be unconstitutional.

the ruling was important in advancing civil rights because it affirmed that the 14th amendment applies to all rights and privileges of citizens, including access to   education.   this was being violated by states whose laws supported the segregation of schools.   section 1 of the 14th amendment reads as follows:
