True False

Step 4:
Find the exact -value using software.

Give your answer to 4 decimal places.
Fill in the blank:
-value _______ .

Explanation / Answer

Answers below:

1. df = n-1 = 25-1 = 24

2. The critical values of t to right and left are = 2.064 and -2.064 respectively ( we assume that alpha = .05 or 95% confidence)

3.t of 1.79 for this test is between 1.711 and 2.064, therefore p-value is between .05<pvalue<.10 [i think the direction of inequality is opposte in question, which is not possible i.e. how is .10<.05 possible ]. Anyway, answer is TRUE

4. The P-Value is .0861. The result is not significant at p < .05.
