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.
'CK,d.f. = t.05,15 = 2.131
(A) S 2 d = Gd2i - (�di)2/n = 2,302.48

(B) to = X2 - Xl .9778

to (.9778) < to,� (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.

(B) t = 3.6908
n
to (3.6908) > tc� (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.
