Background woody plant density (Standard P1). The 2015 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 2015 BRB-2 <br /> background woody plant density exceeds 90% of the standard is shown as follows: <br /> ae- (0.9*technical Standard) <br /> tcalc = <br /> Un) <br /> tcalc = (35.9 — 13.4)/(24.8/Q32)-0.5 ) = 5.132 <br /> Since critical ttabie = 0.853 (one-tailed, alpha = 0.2, 32-1 df) and Laic is greater than this critical <br /> value, reclamation success for background woody plant density for Phase III in 2015 is <br /> demonstrated. It should be noted that the same results would have been achieved using raw values <br /> (tcalc=4.046 which exceeds tt=0.853). Hence the WPD Mandatory standard 1 that there would <br /> be at least 200 woody stems per acre in the background area has been met for 2015. <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 2015 <br /> evaluation is shown as follows: <br /> _ ae- (0.9*techni Cal stand ard) <br /> tGQiG <br /> •"v <br /> tcalc = (35.9 — 30.0)/24.8/32"0.5) = 1.346 <br /> Since critical ttable= 0.853 (one-tailed, alpha = 0.2, 32-1 df) and tcalc is greater than this critical <br /> value, reclamation success for background woody plant density for Phase III in 2015 is <br /> demonstrated. It should be noted that the same results would have been achieved using raw values <br /> (tcalc=2.339 which exceeds tt=0.853).Hence the WPD Mandatory standard 2 has been met for <br /> 2015. <br /> SL-7 - 19 <br />
