Determine the required conservative sample sizes for the following margin of errors using the formula we derived above. Also, discuss the magnitudes of the sample sizes you calculated (especially for very small E) and the relationships between E and n. m: You can easily perform the calculations in SPSS/ Excel and plot :1 versus E for all three condence levels on the same graph. Include this graph in your report. Make sure to round the sample sizes to integers. E n1 90% n 95% n1 99% 0.001 0.002 0.003 0.004 0.005 0.006 0.007 0.008 0.009 0.01 9604 0.02 0.03 0.04 0.05
