###### Question details

Determine the critical values that would be used in testing each of the following null hypotheses using the classical approach. (Give your answers correct to three decimal places.)

(a) *H*_{o}: ρ = 0 vs. *H*_{a}: ρ
≠ 0, with *n* = 18 and α = 0.05

(smaller value)

(larger value)

(b) *H*_{o}: ρ = 0 vs. *H*_{a}: ρ
> 0, with *n* = 32 and α = 0.01

(c) *H*_{o}: ρ = 0 vs. *H*_{a}: ρ
< 0, with *n* = 16 and α = 0.05
