A one-sample t test. The one-sample t statistic for testing H0:μ = 10 Ha:μ > 10 from a sample of n = 20 observations has the value t = 2.10.

(a) What are the degrees of freedom for this statistic?

(b) Give the two critical values t∗ from Table D that bracket t.

(c) Between what two values does the P-value of the test fall?

(d) Is the value t = 2.10 significant at the 5% level?
Is it significant at the 1% level?

(e) If you have software available, find the exact P-value.
