Looking across the row corresponding to 9 degrees of freedom, we see that the t table does not list the value 1.5. We find that P(t > 1.383) = 0.10 and P(t > 1.833) = 0.05. We conclude that 0.05 < P(t > 1.5) < 0.10. See Figure 5.9. A computer package gives the answer correct to three significant digits as 0.0839.
