The t-table has entries for areas of 0.10, 0.05, 0.025, 0.01, and 0.005. In contrast, the ?2-table has entries for those areas and for 0.995, 0.99, 0.975, 0.95, and 0.90. Explain why the t-values corresponding to these additional areas can be obtained from the existing t-table but must be provided explicitly in the ?2-table.
