The calculated value of χ²= 36.30. This is because the chi-square statistic is calculated by summing the squared differences between the observed and expected frequencies, and then dividing by the expected frequencies. In this case, the observed frequencies are 10, 20, and 30, and the expected frequencies are 15, 15, and 15. The squared differences are 25, 25, and 25, and the sum of these is 75. Dividing by the expected frequencies gives a chi-square statistic of 36.30.
