Explanation:
Detailed explanation-1: -What exactly is a confidence interval? A confidence interval is the mean of your estimate plus and minus the variation in that estimate. This is the range of values you expect your estimate to fall between if you redo your test, within a certain level of confidence.
Detailed explanation-2: -Specifically, if a statistic is significantly different from 0 at the 0.05 level, then the 95% confidence interval will not contain 0. All values in the confidence interval are plausible values for the parameter, whereas values outside the interval are rejected as plausible values for the parameter.
