Question

1.Consider the following 2x2 table constructed using data from the 2016 American National Election Survey. Gender Voted for Clinton Voted for Trump Total Man 559 625 1,184 Woman 783 612 1,395 Total 1,342 1,237 2,579 Test to see if there is a difference in the proportion of people who voted for Trump by gender. The standard error from a randomization distribution is .02. Do all steps of a hypothesis test, and use a standard normal distribution to conduct the analysis. Hint: Your test statistic is the z-statistic.

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
