A confidence interval is defined as:
A) a point estimate plus or minus a specific confidence level.
B) a lower and upper confidence limit associated with a specific level of confidence.
C) an interval that has a 95% probability of containing the population parameter.
D) a lower and upper confidence limit that has a 95% probability of containing the population parameter.
Confidence Interval
A statistical range, with a given probability, that is likely to contain the true value of an unknown population parameter.
Population Parameter
A value that accurately represents a particular characteristic of an entire population.
Confidence Level
The probability that a confidence interval will capture an unknown population parameter in repeated samples.

Final Answer :
B
Explanation :
A confidence interval is indeed defined as a range (a lower and upper confidence limit) associated with a specific level of confidence, indicating the interval within which the true population parameter is estimated to lie.
