A chi-square test for independence is conducted for data from a 2 × 2 data matrix with a total of n = 40 participants. If the data produce χ2 = 4.00, then what decision should be made?

a. Reject H0 with α = 0.5 but not with α = .01.

b. Reject H0 with α = 0.1 but not with α = .05.

c. Reject H0 with either α = 0.5 or α = .01.

d. Fail to reject H0 with α = 0.5 or with α = .01.
