the interval 0 < ρ
0
< 1 when the actual correlation is ρ, where 0 < ρ < 1
and ρ
0
= ρ. Figure 9.4a and b illustrated these outcomes for ρ
0
= 0.3 and
ρ
0
= 0.5, respectively.
a. Build a table of numerical values associated with the curves shown in
Figure 9.4a and b.
b. Extend this table to include ρ
0
= 0.1, 0.2, 0.4, 0.6, 0.7, 0.8, 0.9.
