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:

The sample size needed is 40000.

Step-by-step explanation:

The sample size needed is:

[tex]n = \frac{1}{M^{2}}[/tex]

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

This is n when [tex]M = 0.005[/tex]. So

[tex]n = \frac{1}{M^{2}}[/tex]

[tex]n = \frac{1}{0.005^{2}}[/tex]

[tex]n = 40000[/tex]

The sample size needed is 40000.
