Answer: 31
Step-by-step explanation:
Formula to find the sample size is given by :_

, where z*= critical value corresponds to confidence level.
= population standard deviation.
E= Margin of error.
As per given , we have

E=1
We know that critical value corresponding to 95% confidence level = z*=1.96
Then, the required sample size would be :



Hence, the required minimum sample size = 31
