Tegakan Umur 4 Tahun DM4=Diameter di areal Mekanis TM 4=Diameter di areal tumpangsari
Two-Sample T-Test and CI: DM4; DT4 Two-sample T for DM4 vs DT4
N Mean StDev SE Mean DM4 34 18,46 2,38 0,41
DT4 37 18,62 2,68 0,44 Difference = mu DM4 - mu DT4
Estimate for difference: -0,156916 95 CI for difference: -1,361389; 1,047558
T-Test of difference = 0 vs not =: T-Value = -0,26 P-Value = 0,796 DF = 69 Both use Pooled StDev = 2,5414
Kesimpulan :
p-value 0,05, maka tolak Ho atau tidak ada perbedaan yang signifikan antara DM4,DT4
2. Tegakan Umur 4 Tahun TM4=Tinggi di areal Mekanis TT 4=Tinggi di areal
tumpangsari Two-Sample T-Test and CI: TM4; TT4
Two-sample T for TM4 vs TT4 N Mean StDev SE Mean
TM4 34 17,04 1,10 0,19 TT4 37 19,35 1,77 0,29
Difference = mu TM4 - mu TT4 Estimate for difference: -2,30723
95 CI for difference: -3,01208; -1,60239 T-Test of difference = 0 vs not =: T-Value = -6,53 P-Value = 0,000 DF = 69
Both use Pooled StDev = 1,4872 Kesimpulan :
p-value 0,05, maka tolak Ho atau ada perbedaan yang signifikan antara TM4,TT4
3. Tegakan Umur 3 Tahun DM3=Diameter di areal Mekanis DT3=Diameter di areal
tumpangsari Two-Sample T-Test and CI: DM3; DT3
Two-sample T for DM3 vs DT3
N Mean StDev SE Mean DM3 50 13,2
1,44 2,0
DT3 51 14,23 1,92 0,27 Difference = mu DM3 - mu DT3
Estimate for difference: -1,03541 95 CI for difference: -5,06885; 2,99803
T-Test of difference = 0 vs not =: T-Value = -0,51 P-Value = 0,612 DF = 99 Both use Pooled StDev = 10,2140
Kesimpulan
: p-value 0,05, maka terima Ho atau tidak ada perbedaan yang signifikan antara DM3,DT3
4. Tegakan Umur 3 Tahun TM3=Tinggi di areal Mekanis TT 3=Tinggi di areal
tumpangsari Two-Sample T-Test and CI: TM3; TT3
Two-sample T for TM3 vs TT3 N Mean StDev SE Mean
TM3 50 13,2
1,44 2,0
TT3 51 16,24 1,56 0,22 Difference = mu TM3 - mu TT3
Estimate for difference: -3,04129 95 CI for difference: -7,06233; 0,97974
T-Test of difference = 0 vs not =: T-Value = -1,50 P-Value = 0,137 DF = 99 Both use Pooled StDev = 10,1826
Kesimpulan :
p-value 0,05, maka terima Ho atau tidak ada perbedaan yang signifikan antara TM3,TT3
5. Tegakan Umur 2 Tahun DM2=Diameter di areal Mekanis DT2=Diameter di areal
tumpangsari Two-Sample T-Test and CI: DM2; DT2
Two-sample T for DM2 vs DT2 N Mean StDev SE Mean
DM2 51 9,68 2,83 0,40 DT2 53 12,90 1,65 0,23
Difference = mu DM2 - mu DT2 Estimate for difference: -3,22149
95 CI for difference: -4,11772; -2,32527 T-Test of difference = 0 vs not =: T-Value = -7,13 P-Value = 0,000 DF = 102
Both use Pooled StDev = 2,3035 Kesimpulan
: p-value 0,05, maka tolak Ho atau ada perbedaan yang signifikan antara DM2,DT2
