In developing an interval estimate for a population mean, a sample of 50 observations was used. the interval estimate was 19.76
alexandr402 [8]

 

The formula for interval estimate would be: μ = M ± Z(<span>sM</span>)

Where: μ is estimate

M is the mean 

Z is the z value

(<span>sM</span>) is the standard error

 

μ = M ± Z(<span>sM</span>)

n = 200 rather than 50 (√200 = 2√50)

<span>⇒ ME = (1/2) * 1.32 = .66</span>

<span>Using the formula above, plugging this in will give us: μ = 19.76 ± .66</span>

<span> = 19.76  ±  .66 is the confidence interval or interval estimate</span>
