Answer 1

A 90% Confidence Interval can be interpreted as follows:

If we keep on drawing samples from a given population and construct a CI each time and repeat the procedure over a large number of times, then at around 90% of the times, the calculated confidence interval will be able to capture the true value of the population parameter.
