How to find sample standard deviation from confidence interval

Mathematics
1 answer:
belka [17]3 years ago
4 0

Answer:

The standard deviation for each group is obtained by dividing the length of the confidence interval by 3.92, and then multiplying by the square root of the sample size: For 90% confidence intervals 3.92 should be replaced by 3.29, and for 99% confidence intervals it should be replaced by 5.15.
