Answer:
n=42 adult men
Step-by-step explanation:
-The minimum sample size to get a desired margin of error, E is calculated using the formula:
![n\geq( \frac{z\sigma}{E})^2](https://tex.z-dn.net/?f=n%5Cgeq%28%20%5Cfrac%7Bz%5Csigma%7D%7BE%7D%29%5E2)
-Given that
, we can substitute to solve for n in the above formula:
![n\geq (\frac{z\sigma}{E})^2\\\\\therefore n=(\frac{z_{\alpha/2}\sigma}{E})^2\\\\=(\frac{2.58\times7.5}{3})^2\\\\=41.6025\approx42](https://tex.z-dn.net/?f=n%5Cgeq%20%28%5Cfrac%7Bz%5Csigma%7D%7BE%7D%29%5E2%5C%5C%5C%5C%5Ctherefore%20n%3D%28%5Cfrac%7Bz_%7B%5Calpha%2F2%7D%5Csigma%7D%7BE%7D%29%5E2%5C%5C%5C%5C%3D%28%5Cfrac%7B2.58%5Ctimes7.5%7D%7B3%7D%29%5E2%5C%5C%5C%5C%3D41.6025%5Capprox42)
Hence, the desired minimum sample size, n is 42 adult men.
