If n =270 and (p-hat) =0.43, find the margin of error at a 99% confidence level.. give answer to 3 decimals
Troyanec [42]

Answer:

0.078

Step-by-step explanation:

Margin of error = z√(p(1-p)/n)

Given

p-hat = 0.43

n = 270

z at 99% confidence interval = 2.576

Substitute

MOE = 2.576√0.43(1-0.43)/270

MOE = 2.576√0.43*0.57/270

MOE = 2.576√0.2451/270

MOE = 2.576*0.030129

MOE = 0.078

Hence the margin og error is 0.078

The surface area of a cube is 96 square feet. Find the volume of the cube.
Tamiku [17]
<span>cube has six identical walls

96ft</span>²<span> : 6 = 6 ft</span>²<span>  - </span>one wall surface

<span>pattern on the surface of the cube
</span>A = a²
a - <span>the edge of the cube

A = a</span>²    ⇔ a=√A
                  a = √(16ft)² = 4ft
V = volume
V = a³
V = (4ft)³ = 64 ft³
