Use the given data to find the minimum sample size required to estimate the population proportion. margin of error: 0.0080.008

nadezda [96]

Formula for the Minimum Sample size $n=(\frac{z}{E})^2\hat{p}\hat{q}$

The least biased estimate for p and q is 1/2.

$z_{\frac{\alpha }{2}}=z_{{0.01}{2}}=2.58$

Thus

$n=(\frac{2.58}{0.08})^2*0.5*0.5$

$n=260.015$

$n\approx260$

I’m stuck on this question. any help would be greatly appreciated

Mademuasel [1]

Using the Pythagorean theorem we get:

$y^2+8^2=12^2.$

Simplifying the above result we get:

$y^2+64=144.$

Subtracting 64 from the above equation we get:

$\begin{gathered} y^2+64-64=144-64, \\ y^2=80. \end{gathered}$

Therefore:

$y=\sqrt{80}\approx8.9.$

Answer:

$y=8.9.$
