Assume that a sample is used to estimate a population proportion p. Find the margin of error E that corresponds to thegiven statistics and confidence level. Round the margin of error to four decimal places.1)99% confidence; n

Step-by-step explanation:

Given

Required

The margin of error (E)

First, calculate proportion p

Given that:

Calculate the alpha leve;

Divide by 2

Subtract from 1

The corresponding z value is:

So, the margin of error is:

So, we have:

Using a calculator, we have:

Approximate

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12
