Question 1183962: Please help me solve equation.
Calculate the test statistic: X2= Σ (O−E)2E . The observed frequencies from three categories are: 7, 9, 14. Assume that we want to use 0.10 significance level to test the claim that the three categories are equally likely.

χ2 = .

For d.f. = 3 - 1 = 2, p-value = P(χ2 > 2.6) = 0.27 > 0.10, hence do NOT reject the null hypothesis that the three categories are equally likely.
