Let π₁ and π₂ represent the true proportion of workers who would like to attend a self-improvement course in the recent study and the past study, respectively.
-Referring to Table 12-1, what is the critical value when performing a chi-square test on whether the population proportions are different if α = 0.05?

• B) ±1.96
• C) 3.841
