We are C% confident that the interval from ____ to ____ captures the [parameter in context].

Explanation:
Detailed explanation-1: -A 95% CI simply means that if the study is conducted multiple times (multiple sampling from the same population) with corresponding 95% CI for the mean constructed, we expect 95% of these CIs to contain the true population mean.
Detailed explanation-2: -Once the standard error is calculated, the confidence interval is determined by multiplying the standard error by a constant that reflects the level of significance desired, based on the normal distribution. The constant for 95 percent confidence intervals is 1.96.
