Answer:

The test statistic is Z = 1.157

Step-by-step explanation:

Given that:

The sample size n = 1200

The sample proportion of those that will vote for the Republican candidate is represented by $\hat p = \dfrac{x}{n}$

$\hat p = \dfrac{620}{1200}$

$\hat p =0.5167$

The null and the alternative hypothesis can be computed as:

$H_o: P=0.50 \\ \\ H_a :P>0.50$

The formula for the one-sample Z-test for the population proportion can be expressed as:

$Z = \dfrac{\hat p - P_o}{\sqrt{\dfrac{P_o(1-P_o)}{n}}}$

$Z = \dfrac{0.5167 - 0.5}{\sqrt{\dfrac{0.5(1-0.5)}{1200}}}$

$Z = \dfrac{0.0167}{\sqrt{\dfrac{0.5(0.5)}{1200}}}$

$Z = \dfrac{0.0167}{\sqrt{\dfrac{0.25}{1200}}}$

$Z = \dfrac{0.0167}{\sqrt{2.08333333\times10^{-4}}}$

Z = 1.157

describe the transformations that produce the graph of g(x)=1/2(x-4)^3+5 from the graph of the parent function f(x)=x^3. Give th

SSSSS [86.1K]

We have been given a parent function $f(x)=x^{3}$ and we need to transform this function into $g(x)=\frac{1}{2}(x-4)^{3}+5$ .

We will be required to use three transformations to obtain the required function from $f(x)=x^{3}$ .

First transformation would be to shift the graph to the right by 4 units. Upon using this transformation, the function will change to $g(x)=(x-4)^{3}$ .

Second transformation would be to compress the graph vertically by half. Upon using the second transformation, the new function becomes $g(x)=\frac{1}{2}(x-4)^{3}$ .

Third transformation would be to shift the graph upwards by 5 units. Upon using this last transformation, we get the new function as $g(x)=\frac{1}{2}(x-4)^{3}+5$ .
