for this confidence interval for the mean is 100=Z*SD/sqrt(n). To solve for N: sqrt N=Z*SD/1.645‚ now square both sides: N=[Z*SD/100]^2 The Z score for a 90% confidence interval is 1.645. The SD standard deviation is 2500-600=1900 1900/4 N=[1.645*(1900/4)/100]^2=62 A sample of 62 is needed. Your sample data has mean 3.1948 and standard deviation 0.0889‚ with a sample size of 25.
