Please fill in the blank using three decimal places if a numerical answer is required and use NA if a question cannot be answered or there is more than one correct answer. The three main parties and the others got the following primary votes at the last federal election; Coalition 41.4%, Labor 33.3%, Greens 10.4% and Others 14.9%. A recent poll of 1000 people showed that there are 376 people supporting Coalition, 368 people supporting Labor, 116 people supporting greens and 140 people supporting others. Based on the above information, determine whether if the support for any party (or others) has changed since the last election based on this latest poll. Based on the last election, we expect to see people supporting the Coalition in a sample of 1000. The Chi-square test statistic value is , and the corresponding p-value is . An alpha value of 0.04 corresponds to a critical value of , and based on this analysis we (can/cannot) say the support for any party (or others) has changed since the last election. If we compare the population support proportion for Coalition and Labor based on this sample, the p-value will be If we build a 95% confidence interval for the population support proportion for Greens based on this sample, the lower bound will be percent, and we can say that the support for Greens (increased/decreased/stayed the same) since the last election because (in percentage) is (includedot included) within the Cl that we built
