Answer:
The evidence provided does not statistically support the researcher’s belief
Step-by-step explanation:
From the question we are told that
The sample size of each political party is ![n = 200](https://tex.z-dn.net/?f=n%20%20%3D%20200)
The number of democrats that favor death penalty is ![k = 34](https://tex.z-dn.net/?f=k%20%3D%20%2034)
The number of republicans that favor death penalty is ![u = 46](https://tex.z-dn.net/?f=u%20%3D%20%2046)
Generally the sample proportion for Republicans is
![\r p_1 = \frac{ 46}{200}](https://tex.z-dn.net/?f=%5Cr%20p_1%20%3D%20%20%5Cfrac%7B%2046%7D%7B200%7D)
![\r p_1 = 0.23](https://tex.z-dn.net/?f=%5Cr%20p_1%20%3D%20%200.23)
Generally the sample proportion for Democrats is
![\r p_2 = \frac{ 34}{200}](https://tex.z-dn.net/?f=%5Cr%20p_2%20%3D%20%20%5Cfrac%7B%2034%7D%7B200%7D)
![\r p_1 = 0.17](https://tex.z-dn.net/?f=%5Cr%20p_1%20%3D%20%200.17)
The null hypothesis is ![H_o : \r p _1 = \r p_2](https://tex.z-dn.net/?f=H_o%20%20%3A%20%20%5Cr%20p%20_1%20%3D%20%5Cr%20p_2)
The alternative hypothesis is ![H-_1 : \r p_1 > \r p_2](https://tex.z-dn.net/?f=H-_1%20%3A%20%20%5Cr%20p_1%20%3E%20%5Cr%20p_2)
Generally the pooled population proportion is evaluated as
![\r p = \frac{ k + u }{n + n }](https://tex.z-dn.net/?f=%5Cr%20p%20%20%3D%20%20%5Cfrac%7B%20k%20%2B%20%20u%20%7D%7Bn%20%2B%20n%20%7D)
![\r p = \frac{ 34 + 46 }{200 + 200 }](https://tex.z-dn.net/?f=%5Cr%20p%20%20%3D%20%20%5Cfrac%7B%20%2034%20%2B%20%2046%20%7D%7B200%20%2B%20200%20%7D)
![\r p = 0.2](https://tex.z-dn.net/?f=%5Cr%20p%20%20%3D%20%200.2)
The test statistics is evaluated as
![t = \frac{ \r p _1 - \r p_2 }{\sqrt{ \r p (1 - \r p ) [\frac{1}{n} +\frac{1}{n} ]} }](https://tex.z-dn.net/?f=t%20%3D%20%20%5Cfrac%7B%20%5Cr%20p%20_1%20%20%20-%20%20%5Cr%20p_2%20%7D%7B%5Csqrt%7B%20%5Cr%20p%20%20%281%20-%20%5Cr%20p%20%29%20%5B%5Cfrac%7B1%7D%7Bn%7D%20%20%2B%5Cfrac%7B1%7D%7Bn%7D%20%20%5D%7D%20%7D)
![t = 1.5](https://tex.z-dn.net/?f=t%20%3D%201.5)
The p-value is obtained from the z-table the value is
![p-value = P(Z> 1.50 ) = 0.066807](https://tex.z-dn.net/?f=p-value%20%20%3D%20%20P%28Z%3E%20%201.50%20%29%20%3D%20%200.066807)
=> ![p-value = 0.066807](https://tex.z-dn.net/?f=p-value%20%20%20%3D%20%200.066807)
Given that
then we fail to reject the null hypothesis this mean that there is no sufficient evidence to support the researcher’s belief

Answer:
$3029.94
Step-by-step explanation:
We can use the simple interest rate (appreciation) equation: A = P(1 + r)^t
Simply plug in our variables to find our answer:
A = 2400(1 + 0.06)^4
And we should get 3029.94 as our answer!
