1. the answes for the graph ones is the 3rd and 4th graph because both graphs are 1 line and a line is infinite

2. (-3,5) x=(-) y=(+)that means that it must to the left and up part of graph, therefor it is the 4th graph

1. it would be the 4th graph that you didn't show because none of the included answers are correct

Answer:

$n=\frac{0.5(1-0.5)}{(\frac{0.05}{1.96})^2}=384.16$

And rounded up we have that n=385

Step-by-step explanation:

In order to find the critical value we need to take in count that we are finding the interval for a proportion, so on this case we need to use the z distribution. Since our interval is at 95% of confidence, our significance level would be given by $\alpha=1-0.95=0.05$ and $\alpha/2 =0.025$ . And the critical value would be given by:
