A one-sample t test. The one-sample t statistic for testing H0: = 10 Ha: > 10 from a sample of n = 18 observations

A one-sample t test. The one-sample t statistic for testing H0: μ = 10 Ha:μ > 10 from a sample of n = 18 observations has the value t = 1.83.

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

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

(c) What are the right-tail probabilities p for these two entries?

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

(e) Is the value t = 1.83 significant at the 5% level? Is it significant at the 1% level?

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