Another one-sample t test. The one-sample t statistic for testing H0:μ = 60 Ha:μ = 60 from a sample of n = 24 observations has the value t = 2.40.

(a) What are the degrees of freedom for t?

(b) Locate 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 = 2.40 statistically significant at the 5% level? At the 1% level?

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