What is the smallest sample size required to provide a 95% confidence interval for a mean, if it important that the interval be no longer than 1cm? You may assume that the population is normal with variance 9cm2

the smallest sample size required to provide a 95% confidence interval for a mean, if it important that the interval be no longer than 1 cm? You may assume that the population is normal with variance 9cm2. Minimum sample size required is 139. So the minimum sample size should be 35.
