**Estimate and Confidence Interval for College Graduation Time** The data analysis of 42,000 college graduates indicates that the mean time required to graduate with a bachelor's degree is approximately **5.44 years**. This average is calculated with a standard deviation of **1.88 years**. To further explore this data point, a 95% confidence interval is sought for the mean time needed to graduate among all college graduates. This interval provides a range within which the true mean time is expected to lie with a high degree of certainty. The question remains to compute this 95% confidence interval: □ years < μ < □ years *Note: Please ensure to round your answers to two decimal places as necessary.* These statistical estimates allow educational institutions and policymakers to understand typical graduation timelines and better facilitate student success and resource allocation.
