Find the critical value(s) that would be used in a hypothesis test of the following claim.

Claim: "The percentage of Michigan residents who oppose a proposed increase in sales tax to pay for road repairs is not 50%."

A random sample of 725 Michigan residents was collected, and it produced a test statistic of z = -3.58. A significance level of α = 0.02 is to be used.

a. ±2.05 b. ±2.334
c. ±2.586 d. ±2.33
