All else being equal, if you cut the sample size in half, how does this affect the margin of error when using the sample to make

gizmo_the_mogwai [7]

Answer:

The margin of error is multiplied by $\sqrt{2}$

Step-by-step explanation:

margin of error (ME) from the mean can be calculated using the formula

ME= $\frac{z*s}{\sqrt{N} }$ where

z is the corresponding statistic of the given confidence level

s is the standard deviation of the sample (or of the population if it is known)

N is the sample size

Since margin of error is proportional with inverse of $\sqrt{N}$ ,

if we cut the sample size in half, the margin of error is multiplied by $\sqrt{2}$ .

1. The given graph is octagon:

a is the side of the side:

Area of octagon = 2(1+√2) a²= 2(1+√2)(4)²= 77.25 unit²

2. it is similar to Pentagon:

Let A area, l length, w width, b base and h height:

A= lw+1/2b₁h₁+b₂h₂

A= 7(2)+1/2+7*3 =35.5
