Answer:
![Z=-2.87](https://tex.z-dn.net/?f=Z%3D-2.87)
Step-by-step explanation:
From the question we are told that:
Probability on women
![P(W)=65 / 500](https://tex.z-dn.net/?f=P%28W%29%3D65%20%2F%20500)
![P(W) = 0.13](https://tex.z-dn.net/?f=P%28W%29%20%3D%200.13)
Probability on women
![P(M)=133 / 700](https://tex.z-dn.net/?f=P%28M%29%3D133%20%2F%20700)
![P(M) = 0.19](https://tex.z-dn.net/?f=P%28M%29%20%3D%200.19)
Confidence Interval
Generally the equation for momentum is mathematically given by
![Z = \frac{( P(W) - P(M) )}{\sqrt{(\frac{ \sigma_1 * \sigma_2 }{(1/n1 + 1/n2)}}})](https://tex.z-dn.net/?f=Z%20%3D%20%5Cfrac%7B%28%20P%28W%29%20-%20P%28M%29%20%29%7D%7B%5Csqrt%7B%28%5Cfrac%7B%20%5Csigma_1%20%2A%20%5Csigma_2%20%7D%7B%281%2Fn1%20%2B%201%2Fn2%29%7D%7D%7D%29)
Where
![\sigma_1=(x_1+x_2)(n_1+n_2)](https://tex.z-dn.net/?f=%5Csigma_1%3D%28x_1%2Bx_2%29%28n_1%2Bn_2%29)
![\sigma_1=\frac{( 65 + 133 )}{ ( 500 + 700 )}](https://tex.z-dn.net/?f=%5Csigma_1%3D%5Cfrac%7B%28%2065%20%2B%20133%20%29%7D%7B%20%28%20500%20%2B%20700%20%29%7D)
![\sigma_1=0.165](https://tex.z-dn.net/?f=%5Csigma_1%3D0.165)
And
![\sigma_2=1 - \sigma = 0.835](https://tex.z-dn.net/?f=%5Csigma_2%3D1%20-%20%5Csigma%20%3D%200.835)
Therefore
![Z = \frac{( 0.13 - 0.19)}{\sqrt{\frac{( 0.165 * 0.835}{ (500 + 700) )}}}](https://tex.z-dn.net/?f=Z%20%3D%20%5Cfrac%7B%28%200.13%20-%200.19%29%7D%7B%5Csqrt%7B%5Cfrac%7B%28%200.165%20%2A%200.835%7D%7B%20%28500%20%2B%20700%29%20%29%7D%7D%7D)
![Z=-2.87](https://tex.z-dn.net/?f=Z%3D-2.87)
