Astudy found that, in 2005, 12.5% of u. s. workers belonged to unions (the wall street journal, january 21, 2006). suppose a sample of 400 u. s. workers is collected in 2006 to determine whether union efforts to organize have increased union membership. formulate the hypotheses that can be used to determine whether union membership increased in 2006.

Formulate the indicated conclusion in nontechnical terms. be sure to address the original claim. the foundation chair for a hospital claims that the mean number of filled overnight beds is over 523, and she is therefore justified starting a funding campaign to add a wing to the hospital. assuming that a hypothesis test has been conducted and that the conclusion is failure to reject the null hypothesis, state the conclusion in nontechnical terms.
