REQUESTED ASSISTANCE - Would you please review the provided answer as well as the provided detailed explanation / analysis for the answer to the below confidence level / confidence interval question. Is the provided answer correct, and what improvements can be made to the provided detailed explanation / analysis for the answer (please provide substantive / thorough responses)?

As the confidence level increases, the width of the confidence interval increases or decreases or stays the same?

ANSWER: Confidence interval is calculated as statistic +/- critical value*standard error. The critical value increses as the confidence level increases and therefore the width of confidence interval increases. As the confidence level increases, the width of the confidence interval increases (widens).
