When 40 people use the weight watchers diet for one year, their mean weight loss was 3.0 pounds. historically the standard deviation is σ = 4.9 pounds (based on data from "comparison of the atkins, ornish, weight watchers, and zone diets for weight loss and heart disease reduction," by dansinger, et al., journal of the american medical association, vol. 293, no. 1). use a 0.01 significance level to test the claim that the mean weight loss is greater than 0.

a) state the null and alternate hypotheses. (hint: µ = 0)

b) would you perform a left-tailed, right-tailed or two-tailed test? why?

c) compute the test statistic.

d) determine the p-value. (this one is tricky! )

e) would you reject or fail to reject the null hypothesis?

f) interpret your conclusion in the context of this problem.

g) calculate a 99% confidence interval for the average number of pounds lost on this diet. does this interval support your conclusion from your hypothesis test? explain.

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:

all persons born or naturalized in the united states and subject to the jurisdiction thereof, are citizens of the united states and of the state wherein they reside. no state shall make or enforce any law which shall abridge the privileges or immunities of citizens of the united states; nor shall any state deprive any person of life, liberty, or property, without due process of law; nor deny to any person within its jurisdiction the equal protection of the laws.

Our star pitcher, foster enlight, can throw a pitch so fast that it gets to the catcher’s mitt before it leaves foster’s fingers! if the team wins a game then the probability that foster was pitching is 0.8 but only if foster had at least one day’s rest since his last pitching assignment. if foster does not have a day off and the team still wins, the probability that foster was pitching drops by half of what it was on the previous day. if the team wins three games in succession from the toronto tachyons and foster pitched in game #2, what is the probability that he pitched in one or more of the other games? (assume that foster did not pitch on the day before the first game of this three game series.)
