Question

For a Student's t distribution with d.f. = 9 and t = 2.890, consider the following.

(a) Find an interval containing the corresponding P-value for a two-tailed test.

0.0010 < P-value < 0.0100.010 < P-value < 0.020 0.020 < P-value < 0.0500.050 < P-value < 0.1000.100 < P-value < 0.1500.150 < P-value < 0.2000.200 < P-value < 0.2500.250 < P-value < 0.500

(b) Find an interval containing the corresponding P-value for a right-tailed test.

0.0005 < P-value < 0.0050.005 < P-value < 0.010 0.010 < P-value < 0.0250.025 < P-value < 0.0500.050 < P-value < 0.0750.075 < P-value < 0.1000.100 < P-value < 0.1250.125 < P-value < 0.250
