For the hypothesis test H0 7 against H1 7 with variance un

For the hypothesis test H0: = 7 against H1: > 7 with variance unknown and n = 12, approximate the P-value for the test statistic t0 = 2.154. Round your answers to three decimal places (e.g. 98.765).

p

Solution

As H1 used >, this is a right tailed test.

As df = n - 1 = 11, and t0 = 2.154, using table/technology,

P = 0.027134006

or [depending on the table, but this is usually]

0.025 < P < 0.05 [ANSWER]
