The u. s. bureau of labor statistics reports that 11.3% of u. s. workers belong to unions (bls website, january 2014). suppose a sample of 400 u. s. workers is collected in 2014 to determine whether union efforts to organize have increased union membership.

a. formulate the hypotheses that can be used to determine whether union membership increased in 2014. h0: p ha: p

b. if the sample results show that 52 of the workers belonged to unions, what is the p-value for your hypothesis test (to 4 decimals)?

c. at α = .05, what is your conclusion?

should congress have the power to interpret the constitution? write a paragraph in which you argue for or against the wide application of the limplied power

d. i assume the underlined word is "role." reformat if it isn't.

explanation:

role is closest to part because when replacing words, "playing a vital decision," "playing a vital activity," and "playing a vital dollar" don't make logical sense. the only meaningful choice is "playing a vital part."

this fits one of merriam-webster's definitions of role: "a function or part performed especially in a particular operation or process."

well this isn't a question but if you are asking if it is true or false it is, true.
