11) A wildlife conservationist is examining the distribution of animal species in three different regions: A, B, and C. They expect that the distribution should be 30% species X, 40% species Y, and 30% species Z in each region. However, due to habitat changes, they believe that the distribution might be altered. After conducting an extensive survey in each region and gathering data on 800 species, they find the following distribution: ● Region A: X-210, Y-300, Z-290 Region B: X-150, Y - 180, Z-170 Region C: X-90, Y- 120, Z- 190 At a significance level of 0.01, can the conservationist conclude that there are significant differences between the observed and expected species distributions in the three regions?
