- An interval, based on a sample, which has a $95$% probability of containing the unknown population parameter. Note that the interval is variable, but the unknown parameter is fixed.
- Not sure what you mean. the word "significant" is used to describe the p value of 5%, just like "highly significant" is associated with a p value of 1%.
