10. (10 points) Based on the table below, for which measures are there a statistically significant difference between the health-care use of those with any insurance and those with catastrophic coverage in the RAND Health Insurance Experiment? For each measure, explain why or why not.

Column (1) shows the average for the group assigned catastrophic coverage. Columns (2)-(5) compare averages in the deductible, cost-sharing, free care, and any insurance groups with the average in column (1). Standard errors are reported in parentheses in columns (2)-(5); standard deviations are reported in brackets in column (1).
