Background woody plant density (Standard P1). The 2016 BRB-2 woody plant density were first <br /> evaluated for normality using the Shapiro-Francia test. Based on the raw 2015 BRB-2 WPD data <br /> the normality test was not passed. Consequently a square root transformation was performed and <br /> the normality test was passed. Use of a reverse-null t-test of the assertion that the 2016 BRB-2 <br /> background woody plant density exceeds 90% of the standard is shown as follows: <br /> i— (0.9 : rech»:ca: standard) <br /> tca:c = <br /> ( n) <br /> tcalc = (38.3 — 13.4)/(24.6/Q35�-0.5 ) = 5.983 <br /> Since critical ttabie = 0.852 (one-tailed, alpha = 0.2, 35-1 df) and tcalc (5.983) is greater than this <br /> critical value, reclamation success for background woody plant density for Phase III in 2016 is <br /> demonstrated. It should be noted that the same results would have been achieved using raw values <br /> (tcalc=4.315 which exceeds tt=0.852). Hence the WPD Mandatory standard I that there would <br /> be at least 200 woody stems per acre in the background area has been met for 2016. <br /> WPD mandatory standard 2. (Standard P2). Use of a reverse-null t-test of the assertion that the <br /> BRB-2 Background woody plant density exceeds 90% of mandatory standard 2 during the 2016 <br /> evaluation is shown as follows: <br /> x— (0.9:technical standard) <br /> tcalc — <br /> GO <br /> tcalc = (38.3 — 30.0)/24.6/35"0.5) = 1.997 <br /> Since critical ttable= 0.852 (one-tailed, alpha = 0.2, 35-1 df) and tease is greater than this critical <br /> value, reclamation success for background woody plant density for Phase III in 2016 is <br /> demonstrated. It should be noted that the same results would have been achieved using raw values <br /> (tcaic=2.659 which exceeds tt=0.852). Hence the WPD Mandatory standard 2 has been met for <br /> 2016. <br /> SL-7 - 21 <br />
