The value of the z statistic for testing equality of the proportions of streams that fail to meet minimum requirements in the two areas are equal or notisO -2.04ο ο ο οΟ 167Ο -1.490 -0,86αγοραστήπο16 -ho The Virginia Department of Environmental Quality (VDEQ) uses probabilistic monitoring to regulate the water quality of streams in theCommonwealth of Virginia. Of the 85 Eastern Virginia Sites (group 1), 17 do not meet minimum requirements. Of the 80 units sampled in WesternVirginia Sites (group 2), 24 do not meet minimum requirements. Assume the data can be treated as independent simple random samples.The hypotheses to test that the proportions of streams that fail to meet minimum requirements in the two areas are equal or not isO Ho: P1 P2 Vs.
