Answer: 68
Step-by-step explanation:
As per given , we have
Population standard deviation : ![\sigma=4](https://tex.z-dn.net/?f=%5Csigma%3D4)
Critical value for 90% confidence interval =![z_{\alpha/2}=1.645](https://tex.z-dn.net/?f=z_%7B%5Calpha%2F2%7D%3D1.645)
Margin of error : E= 0.8 milligrams
The formula to find the sample size is given by :-
![n=(\dfrac{z_{\alpha/2}\ \sigma}{E})^2](https://tex.z-dn.net/?f=n%3D%28%5Cdfrac%7Bz_%7B%5Calpha%2F2%7D%5C%20%5Csigma%7D%7BE%7D%29%5E2)
i.e. ![n=(\dfrac{(1.645)(4)}{0.8})^2=(8.225)^2](https://tex.z-dn.net/?f=n%3D%28%5Cdfrac%7B%281.645%29%284%29%7D%7B0.8%7D%29%5E2%3D%288.225%29%5E2)
![=67.650625\approx68](https://tex.z-dn.net/?f=%3D67.650625%5Capprox68)
Hence, the limnologist must analyze 68 samples.
