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
The easiest way to do this is the following: if the amount increases with 7% each year, it means that you have to multiply the £400 by 1,07. Then you multiply that answer by 1,07 and one time again. The final answer is 490,0172
