Explanation:

In statistics, a higher - percentage confidence interval (e.g., 95% vs. 90%) is wider. This is because to be more confident (a higher percentage) that the interval contains the true population mean, we need to include a larger range of values. A 90% confidence interval is narrower as it is less "certain" of capturing the true mean, while the 95% interval, by including more possible values, has a higher chance of containing the true population mean.

Answer:

The 95% confidence interval is larger. An interval with a 95% range of values than the 90% confidence interval will be more likely to contain the true population mean.
