./ • • 2 or greater than 15% canopy cover of woody plants relative to total veletative cover. Therefore in the calculation of sample adequacy the applicant~is allowed to utilize an 80% confidence level. Wyoming Fuel has utilized a 90% level which gives an over estimation of the number of samples needed, for 1979 and 1980 cover data for Big Sagebrush and Alkali Sagebrush. 2. It is Division policy to have applicants achieve an accuracy which iswithin 10% of the sample mean. Wyoming Fuel has utilized a 20% accuracy for calculation of sample adequacy for 1979 and 1980 production data for Sig Sagebrush and Alakali Sagebrush. By doing so they have caused themselves to undersample the Alkali Sage Reference area for production (1979, 1980), Alkali Sage permit area for production (1960), the Big Sagebrush permit areafor production (1979), Big Sagebrush Reference area for production (1979), Alkali Sagebrush woody plant densities for reference areas and permit areas (1980), and Big Sagebrush woody plant densities for permit and.~ference areas~(1980). 3. Table SF presents mean values for the Big Sagebrush vegetation type which are different than those values in Table 1F. [dyoming Fuel should clarify this discrepancy. ~ 4. Table 9F values do not correspond to values presented in Tables 1F and 2F. Consistency should be maintained in the method of expressing % values STATISTICAL ANALYSIS (PERMIT vs. REFERENCE) 1. 1979 BIG SAGEBRUSH COVER The analysis was not checked due to the data discrepancy noted above. 2. 1479 ALKALI SAGEBRUSH COVER The applicant has utilized the wrong critical t-value, however this cause the rejection of Ho. The permit and reference areas are dtat equivalent with 95% confidence (c{(2)). not 3. 1980 BIG SAGEBRUSH COVER The applicant has utilized the wrong critical t value which does not affect the outcome. The permit and reference areas are equivalent with 95% confidence (a(2>). I 4. 1980 ALKALI SAGEBRUSH COVER The applicant has utilized the wrong critical t value but has not affected the outcome. The permit and reference areas are equivalent with 95% confidence (a(z)>. ~ 5. 1979 ALKALI SAGEBRUSH PRODUCTION The t-test should not be performed since an adequate sample has not obtained from the reference area, 6. 1979 BIG SAGEBRUSH PRODUCTION The t-test comparison should not be made since an adequate sample was not obtained from the permit area.
