Hi, I've been given the mean and 95% confidence interval (CI) of two independent groups and asked if they were satistically significantly different or not?
I know that if the CIs of the two groups don't overlap at all, then they can be considered as significantly different. However if the CI do overlap, it does not necessarily mean that the two groups are not significantly difference.
Is there any way to determine if the two groups with overlaping CI are significantly difference or not with only the mean and CI? Could we calcuate the p value with?
Here is an example: Group A mean 9.7 with CI 5.7 - 16.4; Group B mean 7.0 with CI 6.7 - 7.4
Thanks!
