Answer:
213 samples needed for 99% confidence interval
Step-by-step explanation:
We know that:
minimum size of sample needed to be sure about total measurement less than 3.5 degree is given as
![n = [\frac{z_{\alpha/2}\times s}{E}]^2](https://tex.z-dn.net/?f=n%20%3D%20%5B%5Cfrac%7Bz_%7B%5Calpha%2F2%7D%5Ctimes%20%20s%7D%7BE%7D%5D%5E2)
where,
s is standard deviation = 19.8 degree
E IS MARGIN OF ERROR = 3.5 degree
right tail critical value of
Z 
so, minimum size of sample needed is
![n = [\frac{2.58\times 19.8}{3.5}]^2](https://tex.z-dn.net/?f=n%20%3D%20%5B%5Cfrac%7B2.58%5Ctimes%2019.8%7D%7B3.5%7D%5D%5E2)
n = 213.02
Therefor 213 samples needed for 99% confidence interval
