You can find the margin of error by using the following formula: Za/2 * σ/√ (n).
Web1 Aug 2024 · So intuitively, if your confidence interval needs to change from 95% level to 99% level, then the value of ‘z’ has to be larger in the latter case. Similarly, for a 90% confidence interval, value of ‘z’ would be smaller than 1.96 and hence you would get a narrower interval. ‘z’ for 90% happens to be 1.64.
