Question

Using the Formula n=1/(ME)2 to Determine Sample Size When we want confidence and use the conservative estimate of , we can use the simple formula to roughly determine the sample size needed for a given margin of error . Use this formula to determine the sample size needed for a margin of error of 0.005 . Enter the exact answer.

Answer 1

The sample size needed is 40000.

Explanation:

The sample size needed is:

`n = (1)/(M^(2))`

Use this formula to determine the sample size needed for a margin of error of 0.005

This is n when
`M = 0.005`. So

`n = (1)/(M^(2))`

`n = (1)/(0.005^(2))`

`n = 40000`

The sample size needed is 40000.
