Now, find the width W as such
In which is the standard deviation of the population and n is the size of the sample.
How large must the sample size be if the width of the 95% interval for mu is to be 1.0:
We need to find n for which W = 1.
We have that , then . So
Rounding up
A sample size of 35 is needed.
