Hypothesis testing about a difference in population proportions between two groups 4. Kira is interested in whether voting choice differs by gender. She wondered if the proportion of women and men who voted for Biden was different in the 2020 presidential election. Using the 2020 National Election Survey, she found the sample proportions as follows: (16.5pts) Males Females P = 0.47 N = 500 N 480 a) Using the significance level of .05, test the null hypothesis that there is no gender difference in proportions voting for President Biden in 2020 elections. (Round all calculations to 3 decimal places) P=0.57 b) Is the difference between the difference in proportions observed between the samples statistically significant? Explain why, using the language of probability c) What is your conclusion? Is there relationship between the variables statistically significant? Interpret the results in terms of the original research question.
