Table D-1. Statistical comparison of sample means based on 1979 production data
for range sites 1, 2, 3, 4 and 5. (1)
Comparison of sample production means of range site 1 vs range site 2 (Table
D-2).
Ho: Range site 1 sample production mean = range site 2 sample production mean.
Ha: Range site 1 sample production mean = range site 2 sample production mean.

to (.9778) < [~ (2.131), therefore cannot reject Ho.
Comparison of sample production means of range site 1 vs range site 3 (Table
D-2).
Ho: Range site 1 sample production mean = range site 3 sample production mean.
Ha: Range site 1 sample production mean = range site 3 sample production mean.

n
to (3.6908) > t~ (2.131), therefore reject Ho.
Comparison of sample production means range site 4 vs range site 5 (Table
D-2).
Ho: Range site 4 sample production mean = range site 5 sample production mean.
Ha: Range site 4 sample production mean = range site 5 sample production mean.
