Solve the problem.
-To test the null hypothesis that the difference between two population proportions is equal to a nonzero
constant c, use the test statistic

z = \frac { \left(\hat { p _ { 1 }} - \hat { p } _ { 2 } \right) - c } { \sqrt { \hat{p _ { 1 } }\left( 1 - \hat{p _ { 1 }} \right) / n _ { 1 } + \hat { p } _ { 2 } \left( 1 - \hat{p _ { 2 }} \right) / n _ { 2 } } }

As long as

\mathrm { n } _ { 1 } \text { and } \mathrm { n } _ { 2 }

are both large, the sampling distribution of the test statistic z will be approximately the
standard normal distribution. Given the sample data below, test the claim that the proportion of male voters
who plan to vote Republican at the next presidential election is 10 percentage points more than the percentage
of female voters who plan to vote Republican. Use the traditional method of hypothesis testing and use a
significance level of 0.05. Men:

\mathrm { n } _ { 1 } = 250 , \mathrm { x } _ { 1 } = 146

Women:

\mathrm { n } _ { 2 } = 202 , \mathrm { x } _ { 2 } = 103

Assume That You Plan to Use a Significance Level Of \alpha
