thank you 1-b. The Virginia Department of Environmental Quality (VDEQ) uses probabilistic moni-toring to regulate the water quality of streams in the Commonwealth of Virginia. Of the 120Eastern Virginia Sites (group 1), 17 do not meet minimum requirements. Of the 80 units sam-pled in Western Virginia Sites (group 2), 24 do not meet minimum requirements. Assume thedata can be treated as independent simple random samples.(3). The hypotheses to test that the proportions of streams that fail to meet minimum require-ments in the two areas are equal or not isa. Ho : P1 = P2 versus H. : P1 < P2.b. Ho : p1 = p2 versus Ha : P1 > P2-c. Ho : P1 = P2 versus H. : P1 + P2.d. Ho : P1 = P2 versus H. : P1 + p2-(4). The value of the z statistic for testing equality of the proportions of streams that fail tomeet minimum requirements in the two areas are equal or not isa. z = -2,62 b. z = -2.72 c. z = -1.96 d. z = -2.33.(5). The researcher tests the following hypotheses Ho : p1 = p2 versus H. : p1 # p2. The 90%confidence interval isa. -0.158 + 0.096b. -0.158 + 0.099c. -0.158 ±0.077d. -0.158 +0.075
