Let the test statistic T have a t distribution when H0 is true. Give the P-value for each of the following situations. (Round your answers to three decimal places.)

(a) Ha: μ > μ0, df = 16, t = 2.962
P-value = ?
(b) Ha: μ < μ0, n = 30, t = 2.341
P-value = ?
(c) Ha: μ ≠ μ0, n = 36, t = −1.291 or t = 1.291
P-value = ?

Answer:

Step-by-step explanation:

Let the test statistic T have a t distribution when H0 is true. Give the P-value for each of the following situations. (Round your answers to three decimal places.)

(a) Ha: μ > μ0, df = 16, t = 2.962

This is one tailed

P-value = 0.004589

(b) Ha: μ < μ0, n = 30, t = 2.341

This is one tailed

P-value = 0.013158

(c) Ha: μ ≠ μ0, n = 36, t = −1.291 or t = 1.291

This is two tailed

P-value = 0.102466
