Question 350252
What is the difference between a point estimate and a confidence interval estimate? 
---
A point estimate is some sample statistic such as sample mean, or
sample proportion.
A confidence interval estimate is a derived interval around a
sample mean or sample proportion that may or may not contain the
population mean or population proportion.
--------------------------------------

Does the confidence interval always contain the true population parameter? Yes or No.  No is the correct answer.
--------
Interpret what is meant by a 95% confidence interval.
Using the method prescribed we can state with 95% confidence
that the interval does contain the population parameter.
