Assume z_crit = +1.65 with α = .05 and z_crit = +2.33 with α = .01. Assume further that z_obt = +2.02. The correct statistical decision would be to A) fail to reject H₀ at both α = .05 and α = .01. B) reject H₀ at both α = .05 and α = .01. C) reject H₀ at α = .05 but fail to reject H₀ at α = .01. D) reject H₀ at α = .01 but fail to reject H₀ at α = .05.

The obtained value z_obt = +2.02 is greater than the critical value for α = .05 (+1.65) but less than the critical value for α = .01 (+2.33), leading to rejection of H₀ at α = .05 but not at α = .01.
