Explanation / Answer

# Chegg policy states that if multiple questions are there to answer the first question

1) Yes population parameters can be estimated using an interval estimate. We call this interval estimate as our confidence interval, based on the significance level, we may be 90%, 95% or even 99% confidence that the true population parameter lies in our interval estimate.

For eg if our confidence interval is 95%, then we are 95% confident that the true population parameter lies in our confidence interval.

Thus, the answer is TRUE
