Ivahew [28]

Answer:

n=3.8416≅4

So Minimum Sample Size is 4

Step-by-step explanation:

In order to find the minimum sample size, the formula we use will be:

n= \frac{Z^2*S^2}{E^2}

Where:

n is sample size  

Z is the distribution

S is the standard deviation

E is the  Margin of error

S=3 ,E=3

For Z:

Alpha=1-0.95=0.05

Alpha/2=0.025=2.5%

From Cumulative Standard Distribution Table:

Z at Alpha/2 = 1.960

n= \frac{1.960^2*3^2}{3^2}

n=3.8416≅4

So Minimum Sample Size is 4

Given that the two lines are parallel, we can assume that the two angles given are supplementary (due to them being same side interior angles)

Supplementary angles - when the sum of their degree measure is 180°

8x - 13 + 4x + 1 = 180

12x = 192

x = 16
