A random sample of 500 males included 215 that approved of the performance of a President. A random sample of 500 females included 185 that approved of the performance of a President. Determine each of the following parts that will lead you to construct a 95% confidence interval for the overall difference in the percentage of males and females that approve of the President's performance. Group one males, group 2 females Calculate p-hat 1 and q-hat 1, Calculate p-hat 2 and q-hat 2 , Calculate (p-hat 1 - p-hat 2) And Find the critical z-score for a 95% level of confidence
