<br />Ho: y ~ c <br />Ha: yG c <br />Employing the t test fora one tailed comparison: <br />t = X - C <br />SX <br />Where: <br />c = 0.9,u the revegetation standard (90% of historic record) <br />,u = standard mean determined from historic record <br />z = sample mean at year 9 or 10 <br />SX = standard error of the mean defined as S2/n <br />tcalc is then compared with ttable at oC = 0.10, and n-1 degrees of freedom <br />If tcalc is greater than or equal to ttable Ho is rejected and the <br />revegetation is not successful. <br />6) Trapper proposed that the average of the last two consecutive years of <br />herbaceous production must be greater than the standard to conclude that <br />revegetation is successful. Rule 4.15.7(5) requires that, "the <br />revegetation success criteria...shall be met for at least the last two <br />consecutive years...". Therefore, the actual sampled values for <br />herbaceous production must meet the standard individually (not an <br />average) for the last two consecutive years of the liability period. <br />If you have any questions, please contact me. <br />9956E <br />/lal <br />
