FOR NEXT 3 QUESTIONS USE THE 1. Neuroinvasive West Nile |
Show transcribed image text Neuroinvasive West Nile virus refers to a severe disease that affects a person's nervous system. It is spread by the Culex species of mosquito. In the United States in 2010 there were 629 reported cases of neuroinvasive West Nile virus out of a total of 1021 reported cases, and there were 486 neuroinvasive reported cases out of a total of 712 cases reported in 2011. Can we conclude that the 2011 proportion of neuroinvasive West Nile virus cases is significantly more than the 2010 proportion of neuroinvasive West Nile virus cases? If you conduct hypothesis testing, you have to consider: A.a test of two proportions B.a test of two independent means C.a test of a single mean D.a test of a single proportion. 2.0 Points An appropriate null hypothesis for this test is: A.p 2011 = p 2010 B.p 2011 > p 2010 C.? 2011 = ? 2010 D.p 2011
